Synthesis of Magnetically Recoverable Nickel (II) Complex-Functionalized Fe3O4@ISNA (ISNA= Isonicotinic acid) Nanomaterials: Catalytic Studies on Nitrophenol Reduction and TD- DFT Studies
Abstract: In this study, we aimed to develop a novel, environmentally sustainable, and magnetically separable heterogeneous nanocatalyst, denoted as Fe3O4@ISNA@NiL (where L represents the ligand). The synthesis involved a two-step process, first, isonicotinic acid was chemically grafted onto the surface of iron oxide nanoparticles (Fe3O4) to introduce functional groups capable of further chemical modification. Subsequently, a nickel(II) Schiff base monomeric complex was anchored onto the modified surface, resulting in a nanocatalyst …

Synthesis of Biodiesel from Biowaste/Vegetable Oil by Using Heterogeneous Nano-Catalyst
Abstract: This paper presents preparation of heterogeneous nanocatalyst (NaOH/ZnO-Li2CO3) for biodiesel synthesis from biowaste/vegetable oil by transesterification. Transesterification is an important reaction that produces fatty acid methyl esters which are excellent substitutes for diesel fuel. Biodiesel production by using nanocatalyst is one of important approaches in the biofuel research. The optimization of transesterification reaction is affected by the catalyst type, reaction temperature, reaction time, methanol to biowaste/oil ratio. The analysis of …

Nanostructured Catalysts for Sustainable CO2 Reduction: Advancing Green Chemistry and Polymer Composites
Abstract: This study provides a comprehensive analysis of advanced nanostructured catalysts designed to enhance the efficiency of artificial photosynthesis for sustainable fuel production. We systematically evaluated a range of nanomaterials—including metal oxides, plasmonic nanoparticles, and carbon-based composites—to determine their effectiveness in converting solar energy into storable chemical fuels. The catalysts were synthesized via sol-gel, hydrothermal, and green methods, and their properties were thoroughly characterized using XRD, SEM, TEM, UV-Vis spectroscopy, and …
