ACS Applied Materials and Interfaces, 2025
We present a green procedure for the synthesis of metal-organic frameworks (MOFs) (having Zn, Ni, or Co) in graphene oxide aqueous suspensions (obtained with graphitized or nongraphitized carbon nanofibers) avoiding organic solvents and high temperatures. The materials were thoroughly characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), N2/CO2-physisorption, Raman and X-ray photoelectron (XPS) spectroscopies. The results demonstrate that the nature of the metal (electronegativity) and graphene oxide (defects of oxygen-containing groups) are key in the size, porosity, and defectivity (free noncoordinated linkers and open metal sites) of the MOF and significantly affect their CO2 adsorption energy (up to 6 kJ·mol-1 increase), uptake (up to 5·mmolCO2·g-1 increase), and catalytic activity (up to 35% rate increase) with respect to bulk MOFs in the solvent-free, ambient pressure CO2 cycloaddition to epoxides.

Chempluschem, 2023
The introduction of iron ionic sites by metal exchange of defective homometallic nickel pyrazolate frameworks generates non‐precious, Earth‐abundant, first‐row heterometallic Fe/Ni‐pyrazolate frameworks. The Fe incorporation at the Ni nodes of the framework allows to control the hydrogen peroxide activation, minimizing its decomposition and O2 liberation, occurring at the homometallic Ni nodes. The generation of Fe−OH reactive oxygen species at the heterometallic Fe/Ni nodes is demonstrated by the higher activity in the proof‐of‐concept oxidation of 1‐phenylethanol to acetophenone in an aqueous medium.
Layer-by-Layer Integration of Zirconium Metal-Organic Frameworks onto Activated Carbon Spheres and Fabrics with Model Nerve Agent Detoxification Properties
Rodrigo Gil-San-Millan, Pedro Delgado, Elena Lopez-Maya, Javier D. Martin-Romera, Elisa Barea, et al.
ACS Applied Materials and Interfaces, 2021
We report the controlled synthesis of thin films of prototypical zirconium metal–organic frameworks [Zr6O4(OH)4(benzene-1,4-dicarboxylate-2-X)6] (X = H, UiO-66 and X = NH2, UiO-66-NH2) over the external surface of shaped carbonized substrates (spheres and textile fabrics) using a layer-by-layer method. The resulting composite materials contain metal–organic framework (MOF) crystals homogeneously distributed over the external surface of the porous shaped bodies, which are able to capture an organophosphate nerve agent simulant (diisopropylfluorophosphate, DIFP) in competition with moisture (very fast) and hydrolyze the P–F bond (slow). This behavior confers the composite material self-cleaning properties, which are useful for blocking secondary emission problems of classical protective equipment based on activated carbon.
Selective Implantation of Diamines for Cooperative Catalysis in Isoreticular Heterometallic Titanium–Organic Frameworks
Elena López‐Maya, Natalia M. Padial, Javier Castells‐Gil, Carolina R. Ganivet, Ana Rubio‐Gaspar, et al.
Angewandte Chemie International Edition, 2021
We introduce the first example of isoreticular titanium-organic frameworks, MUV-10 and MUV-12, to show how the different affinity of hard Ti(IV) and soft Ca(II) metal sites can be used to direct selective grafting of amines to the last. This enables the combination of Lewis acid titanium centers and available -NH2 sites in two sizeable pores for cooperative cycloaddition of CO2 to epoxides at room temperature and atmospheric pressure. The s elective grafting of molecules to heterometallic clusters adds up to the pool of methodologies available for controlling the positioning and distribution of chemical functions in precise positions of the framework required for definitive control of pore chemistry.
Diffusion Control in Single-Site Zinc Reticular Amination Catalysts
Francisco G. Cirujano, Elena López-Maya, Neyvis Almora-Barrios, Ana Rubio-Gaspar, Nuria Martín, et al.
Inorganic Chemistry, 2020
Zn-containing metal-organic frameworks have been used for the first time as heterogeneous catalysts in the amination of C-Cl bonds. The use of extended bis(pyrazolate) linkers can generate highly porous architectures, which favor the diffusion of amines to the confined spaces with respect to other imidazolate frameworks with narrower pore windows. The N4Zn nodes of the Zn-reticular framework show comparable activity to state-of-the-art homogeneous Zn amination catalysts, avoiding the use of basic conditions, precious metals, or other additives. This is combined with long-term activity and stability upon several reaction cycles, without contamination of the reaction product.
Magnesium Exchanged Zirconium Metal-Organic Frameworks with Improved Detoxification Properties of Nerve Agents
Rodrigo Gil-San-Millan, Elena López-Maya, Ana E. Platero-Prats, Virginia Torres-Pérez, Pedro Delgado, et al.
Journal of the American Chemical Society, 2019
UiO-66, MOF-808 and NU-1000 metal-organic frameworks exhibit a differentiated reactivity to-wards [Mg(OMe)2(MeOH)2]4 related to the accessi-bility of the pore structure. Microporous UiO-66 remains unchanged while mesoporous MOF-808 and hierarchical micro/mesoporous NU-1000 mate-rials give rise to the formation of doped systems containing exposed MgZr5O2(OH)6 heterometallic clusters in the mesoporous cavities. This modifica-tion is responsible for a remarkable enhancement of the catalytic activity towards the hydrolytic degra-dation of P-F and P-S bonds of toxic nerve agents, at room temperature, in unbuffered aqueous solutions.
