2D Trimetal-organic framework derived metal carbon hybrid catalyst for urea electro-oxidation and 4-nitrophenol reduction

MoS2 Decoration Followed by P Inclusion over Ni-Co Bimetallic Metal–Organic Framework-Derived Heterostructures for Water Splitting

“…Metal–organic frameworks (MOFs) are comparatively new and emerging crystalline porous materials with an attractive structure, where the metal-ion clusters are firmly coordinated with organic spacers. , MOFs have been employed as templates for constructing porous materials because of its high porosity, versatile design, and large surface area. − The carbon-based materials, significantly enriched with the heteroatoms, are frequently used as supporting materials for other heterogeneous catalysts owing to their stability and recyclability. − Although such a mesoporous carbon framework limits diffusion and mass transport, the rationally designed metal-ion, organic clusters deliver multifunctional active sites and improved electrical conductivity. , Some of the exciting reports have already demonstrated the influences of heteroatom and metal/metal oxide nanoparticle doping on carbon hybrids in water splitting. − The pristine MOF and its derivatives are widely studied in different applications, including gas adsorption, separation, hydrogen storage, and heterogeneous catalysis. − In addition, heteroatom-doped porous carbon derived from MOFs and their composites, for instance, MOF/graphene, Pt nanoparticles @ MOF, and metal/metal oxide composites, has also been studied in the field of energy storage and conversions. − Of late, MOF-derived carbon materials make a significant contribution, especially in the area of electrocatalysis, because of their high conductivity, stability, and the copious amount of active carbon sites nearby the heteroatom.…”

One pot synthesis and characterization of binary and ternary metal organic frameworks (MOFs) as tri-modal catalysts for thiophene electrooxidation, water splitting and 4-nitrophenol reduction

“…Both bimetallic and trimetallic MOFs were synthesised based on the previously reported procedure. 14 The equimolar amounts of cobalt( ii ) nitrate hexahydrate, aluminum nitrate hexahydrate, nickel nitrate hexahydrate, benzene tricarboxylic, and 4,4′-bipyridine were added into a beaker containing 80 mL of N , N -dimethylformamide (DMF). This mixture was then poured into a Teflon autoclave reactor and kept at 120 °C for 24 h. Then the solution was allowed to cool to room temperature.…”

“…11,12 Because the active site is more accessible for chemical reactions, the synergetic effect of various valence metals can considerably improve the electrocatalytic activity of MOFs. 10,13–15 Recent advances in multi-metallic metal organic frameworks (MM-MOFs) and their derivatives for the electrochemical biosensor application are well documented. 4…”

Highly Sensitive and Selective Eco-Toxic 4-Nitrophenol Chemical Sensor Based on Ag-Doped ZnO Nanoflowers Decorated with Nanosheets

“…Nitrophenol is a common intermediate product used for the production of analgesic, dyes, medicines, leather products, and so on. It is considered a hazardous pollutant in food chains such as fruits, and cultivation crops [ 7 , 8 , 9 , 10 ]. Nitrophenol compounds also cause severe environmental pollution, owing to their highly toxic level for humans and animals, and thus have been included in the list of toxic and harmful pollutants in different countries.…”
