Deciphering the role of pristine and Ni ions substituted Co3O4 nanoparticles with altered structural, magnetic and dielectric traits towards elevated photosensing and photocatalytic activity R. Sylvia Reena, A. Aslinjensipriya, S. Grace Infantiya, R. Ragu, M. Jose, S. Jerome Das International Journal of Environmental Analytical Chemistry, 2024 Pure and nickel (Ni) doped cobalt oxide nanoparticles were employed by the co-precipitation method to present the structural, optical, and photocatalytic characteristics of NixCo3-xO4 nanoparticles (x = 0, 0.05, 0.1, and 0.3) for organic pollutant photodegradation. X-ray diffraction (XRD) was employed on NixCo3-xO4 samples with particle sizes ranging from 14 to 22 nm, confirming the occurrence of cubic phase. In addition, particle size was calculated by Debye Scherrer, Williamson-Hall (W-H) and Halder methods, respectively. The Fourier transform infrared (FTIR) analyses of all samples characterised the inherent lattice vibrations of spinel structures octahedral and tetrahedral sites, respectively. FESEM image depicts irregular-shaped clusters and EDX confirmed the presence of Ni, Co and O elements. The mesoporous nature of the pores and high BET specific surface area indicated the presence of several active sites, proving their viability as photocatalysts. UV-Vis spectrophotometer was utilised to measure the optical properties, which included recording absorption spectra and computing optical parameters. The photocatalytic activities of the pure Co3O4 and NixCo3-xO4 photocatalysts were studied by the degradation of a series of four dyes (Congo Red, Tartrazine, Rhodamine B, and Methylene Blue) solution under visible light irradiation. Compared to pure cobalt oxide, Ni-incorporated Co3O4 exhibits a substantially higher photocatalytic efficiency that increases with Ni doping concentration. The photocatalysts displayed superior recycling stability, retaining high performance after three cycles. The photosensing properties were investigated under UV light, and a considerable photocurrent enhancement was observed. As a result, it is illustrated that Ni-doped cobalt oxide NPs are a potential material for the fabrication of photosensitive devices.
Investigation on growth, structural and physico-chemical traits of 4-N, N-dimethylamino-4′-N'-phenyl-stilbazolium hexafluorophosphate (DAPSH) crystal A. Surya Prabha, R. Ragu, J. Reena Priya, J. Mary Linet, J. Arul Martin Mani Chemical Physics Impact, 2023 An organic salt 4-N,N-dimethylamino-4′-N’-phenyl-stilbazolium hexafluorophospate (DAPSH) was synthesized by metathesization process using acetonitrile solvent and DAPSH was crystallized by slow evaporation method. Single crystal X-ray diffraction (SXRD) analysis of DAPSH crystal revealed that the crystal possesses monoclinic crystal system with the non-centrosymmetric space group Cc. The existence of various functional groups present in the titular material is affirmed using FTIR analysis. UV–vis-NIR spectral analysis revealed the optical absorption of DAPSH crystal and the band gap as 3.1 eV. The elemental percentage composition was verified by CHN and EDAX analysis. Vickers Microhardness testing was used to assess the mechanical stability of the produced crystal. The DAPSH crystal is stable up to 250 °C, according to thermal analysis. The Kurtz and Perry NLO test confirms DAPSH's second harmonic generation (SHG) ability. The dielectric measurement was conducted in the frequency range from 50 Hz to 5 MHz for different temperatures (313, 323, 373, 423 and 473 K). The crystal exhibited low dielectric loss in the high frequency region and AC conductivity was calculated from the dielectric data. The anticancer and toxicity properties of the produced DAPSH crystal were investigated and it was confirmed to be an effective substance against cancer cells.
