Nanocatalysis is a rapidly growing area in the field of chemistry. Despite of significant progress, there have been associated challenges with the reduced usage, generation of hazardous substances and their potential effect on human health and environment. With this perspective, my research group have designed and fabricated various metal nanocomposites (such as Cu, Pd, Ni, Mn, and Zn) supported on magnetite nanoparticles. The developed materials exhibit numerous advantages including excellent recyclability, high selectivity, ease of recovery via the aid of an external magnet due to the presence of a superparamagnetic Fe3O4 core material. The core is being surrounded by a shell made up of silica that prevent the nanoparticles from agglomerating and undergoing oxidation. These nanoparticles have been used in various applications and utilised as catalyst in various chemical transformations. These organic-inorganic hybrid nanocatalysts have been characterised by different physico-chemical techniques such as VSM, XRD, XPS, SEM, TEM, ICP, ED-XRF and FT-IR. The catalytic activity, performance and features have been investigated by optimizing various organic reactions for the synthesis of industrially important compounds and derivatives. Synthesized catalysts have been effortlessly recycled. Hence, magnetic nanocatalysts are the potential candidates for environmental and economic concern as they have simple workup procedure, cost effective and lead to zero effluent discharge to the environment.
