    MoS x Se (2− x ) and MoSe x Te (2− x ) solid solutions with various S:Se and Se:Te ratios have been prepared by high temperature solid-state reactions, and thinned down to few-layers by Li-intercalation followed by exfoliation. Photocatalytic as well as electrocatalytic hydrogen evolution reaction (HER) activity of exfoliated MoS x Se (2− x ) /MoSe x Te (2− x ) 2D nanosheets have been studied. It is found that Se-rich compositions exhibit good HER activity. The MoS 0.5 Se 1.5 nanosheets show high photocatalytic HER activity yielding 29.6 mmol h −1  g −1 of H 2 , while MoS 1.0 Se 1.0 displays good electrocatalytic activity with an onset potential of −0.220 V. Amongst MoSe x Te (2− x ) solid solutions, MoSe 1.8 Te 0.2 shows relatively high photocatalytic HER activity (5.0 mmol h −1  g −1 ), while MoSe 1.0 Te 1.0 exhibits a low onset potential (−0.190 V vs . RHE).

  • Enhanced visible-light-assisted photocatalytic hydrogen generation by MoS<inf>2</inf>/g-C<inf>3</inf>N<inf>4</inf> nanocomposites
    C.M. Nagaraja, Manjodh Kaur, and Suman Dhingra

    International Journal of Hydrogen Energy, ISSN: 03603199, Pages: 8497-8506, Published: 18 March 2020 Elsevier BV
    Abstract A facile, one-pot, solvothermal synthesis of MoS2 microflowers (S1) and the heterostructures MoS2/g-C3N4 with varying ratios of 1:1 (S2), 1:2 (S3) and 1:3 (S4) exhibiting enhanced visible-light-assisted H2 generation by water splitting has been reported. The compounds were thoroughly characterized by PXRD, FESEM, HRTEM, EDS, UV–vis and XPS techniques. FESEM and HRTEM analyses showed the presence of microflowers composed of nano-sized petals in case of pure MoS2 (S1), while the MoS2 microflowers covered with g-C3N4 nanosheets in case of MoS2/g-C3N4 heterostructure, S4. XPS analysis of S2 showed the presence of 2H phase of MoS2 with g-C3N4. The Eosin-Y/dye-sensitized visible-light-assisted photocatalytic investigation of the samples in the absence of any noble metal co-catalyst revealed very good water splitting activity of MoS2/g-C3N4 heterostructure, S2 with hydrogen generation rate of 1787 μmol h−1g−1 which is about 6 and 40 times higher than pure MoS2 and g-C3N4 respectively. The relatively higher catalytic activity of the heterostructure, S2 has been ascribed to the efficient spatial separation of photo-induced charge carriers owing to the synergistic interaction between MoS2 and g-C3N4. A possible mechanism for the Eosin-Y-sensitized photocatalytic H2 generation activity of MoS2/g-C3N4 heterostructures has also been presented. The enhanced activity of S2 was further supported by fluorescence measurements. Thus, the present study highlights the importance of non-noble metal based MoS2/g-C3N4 heterojunction photocatalysts for efficient visible-light-driven H2 production from water splitting.

    van der Waals heterostructures formed by 2D materials have attracted much attention in the last few years. Recently, 2D nanosheets linked by covalent bonds have been found to exhibit novel properties. In the present study we have investigated supramolecular layered heterostructures formed by nanosheets of MoS2 with BC7 N, g-C3 N4 and graphene. These materials have been synthesized via a non-covalent host-guest synthetic design using cucurbit[8]uril (CB[8]) hosts. In addition to offering reversible disassembly, these heterostructures show good visible-light-driven hydrogen evolution reaction (HER) activity as well as reasonable gas adsorption and other properties.

  • Supramolecular Hybrids of MoS<inf>2</inf> and Graphene Nanosheets with Organic Chromophores for Optoelectronic Applications
    Manjodh Kaur, Navin Kumar Singh, Aritra Sarkar, Subi J. George, and C. N. R. Rao

    ACS Applied Nano Materials, eISSN: 25740970, Pages: 5101-5107, Published: 28 September 2018 American Chemical Society (ACS)
    A novel supramolecular strategy based on host–guest chemistry has been proposed for the noncovalent functionalization of MoS2 nanosheets with organic chromophores. Stable ternary complexes are formed between benzyl imidazole functionalized MoS2 and chromophores in the presence of cucurbit[8]uril host, resulting in noncovalent anchoring of donor and acceptor chromophores on the surface. On the other hand, in the case of graphene, we observe π–π stacking resulting in the face-on organization of chromophore on the surface. The MoS2 and graphene hybrids have been characterized by various spectroscopic techniques. The present design opens up new possibilities for the noncovalent functionalization of transition metal dichalcogenides even in the absence of delocalized π-electrons which are essential to alter their optoelectronic properties. In addition, these novel supramolecular hybrid materials with strong electronic communication between noncovalently anchored chromophores and the 2D nanosheets may find appli...

    ACS Sustainable Chemistry and Engineering, eISSN: 21680485, Pages: 4293-4303, Published: 1 May 2017 American Chemical Society (ACS)
    A facile, one-pot, solvothermal synthesis of nanocrystals (NCs) of Zn1–xCdxS (x = 0.1 (S1)–0.9 (S9)) solid solutions has been successfully carried out using 4,4′-dipyridyldisulfide (DPDS = (C5H4N)2S2)) as a new temperature-dependent in situ source of S2– ions. Powder XRD patterns of the samples revealed gradual phase transformation from cubic to hexagonal upon increasing the Cd content (x) in the solid solutions Zn1–xCdxS (0 ≤ x ≤ 1). FESEM analyses showed almost spherical morphology of the solid solutions, S2, S5, and S9. HR-TEM analyses of S3 and S9 unveiled the presence of small nanocrystals (NCs) of size 7 and 15 nm, respectively, and highlights the discontinuity in the pattern of lattice fringes. Optical measurements revealed that Zn1–xCdxS solid solutions exhibit precisely tunable band structure with varying the concentration of Cd content. Furthermore, visible-light-assisted photocatalytic investigation revealed very good activity of the Zn0.7Cd0.3S solid solution for water splitting with H2 genera...

  • Nanocomposites of 2D-MoS<inf>2</inf> nanosheets with the metal-organic framework, ZIF-8
    K. Pramoda, Manjodh Kaur, Uttam Gupta, and C. N. R. Rao

    Dalton Transactions, ISSN: 14779226, eISSN: 14779234, Pages: 13810-13816, Published: 2016 Royal Society of Chemistry (RSC)
    The nanocomposites of MoS2 nanosheets with the metal-organic framework, ZIF-8, have been synthesized starting with the layers of 1T-MoS2 generated by Li intercalation of bulk MoS2, followed by exfoliation. The nanocomposites contain the Zn-S bond and exhibit reasonably high surface areas. They exhibit CO2 uptake higher than ZIF-8. Heating the nanocomposites to 900 °C under a N2 atmosphere yields MoS2-ZnS nanocomposites which show good activity for the visible-light induced hydrogen evolution reaction.

  • Green Synthesis of a Microporous, Partially Fluorinated Zn<sup>II</sup> Paddlewheel Metal-Organic Framework: H<inf>2</inf>/CO<inf>2</inf> Adsorption Behavior and Solid-State Conversion to a ZnO-C Nanocomposite
    Sandeep Singh Dhankhar, Manjodh Kaur, and C. M. Nagaraja

    European Journal of Inorganic Chemistry, ISSN: 14341948, eISSN: 10990682, Volume: 2015, Pages: 5669-5676, Published: 1 December 2015 Wiley
    A microporous, partially fluorinated metal–organic framework consisting of ZnII dimeric paddlewheel units, formulated as [Zn(hfipbba)(4bpdb)0.5]·H2O (1) [hfipbba = 4,4′-(hexaflouroisopropylene)bis(benzoic acid); 4bpdb = 1,4-bis(4-pyridyl)-2,3-diaza-1,3-butadiene], was synthesized by room-temperature self-assembly and characterized structurally by single-crystal XRD. Compound 1 adopts a 3D microporous framework structure constituted by six-connected ZnII dimeric paddlewheel nodes with {44.610.8}-net topology. Further, rapid synthesis of phase-pure 1 by green synthetic approaches such as mechanochemical and sonochemical routes was achieved. The 3D framework of 1 houses 1D helical channels with narrow pore dimensions of about 3.11 × 4.17 A and exhibits interesting gas-uptake (H2/CO2) properties. The isosteric heats of adsorption Qst for H2 and CO2 were estimated to be 8.8 and 36.4 kJ mol–1, respectively. Interestingly, solid-state conversion of 1 to phase-pure hexagonal ZnO nanocrystals of 6.1 ± 0.63 nm in size, embedded in carbonaceous layers to form a ZnO–C nanocomposite (NC), occurred on heating of 1 to 600 °C under vacuum for 2 h. The ZnO–C NC was characterized by XRD, UV/Vis, energy-dispersive X-ray, and TEM analyses. The as-synthesized ZnO–C NC exhibits good photocatalytic activity for the degradation of methylene blue.

    Materials Letters, ISSN: 0167577X, eISSN: 18734979, Volume: 154, Pages: 90-93, Published: 1 September 2015 Elsevier BV
    Abstract A facile, one-pot, template-free solvothermal route for the synthesis of ZnS microspheres composed of nanocrystals (NCs) using 4,4′-dipyridyldisulfide (DPDS=(C5H4N)2S2) as a new in situ source of S2− ions without the use of capping agent has been presented. Powder X-ray diffraction measurements of the samples revealed the hexagonal structure of the ZnS NCs. FESEM and TEM analyses unveiled the spherical morphology of ZnS microspheres composed of NCs with diameter of 15–20 nm. Optical investigation showed that ZnS NCs have an UV–vis absorption at 250 nm which is blue-shifted compared to that of bulk ZnS and the calculated value of band gap is 4.6 eV. Photocatalytic investigation of the ZnS NCs showed very good photocatalytic activity for degradation of methyl orange (MO) dye.

    Abstract Cadmium sulfide (CdS) microspheres composed of CdS nanocrystals were synthesized by a one-pot solvothermal method using a new in situ S 2− source and without the use of any template or capping agent. The powder X-ray diffraction measurements revealed the cubic structure of the CdS microspheres. SEM analyses indicated that the CdS microspheres are further composed with assembled CdS nanocrystals. TEM analyses revealed the crystallites size of about 15–20 nm. Optical investigation showed that the obtained CdS microspheres have an UV–vis absorption at 420 nm which is blue-shifted compared to that of bulk CdS and the calculated band gap value is 2.52 eV. Photocatalytic investigation of the CdS microspheres showed good photocatalytic activity for photodegradation of methylorange (MO) dye.
