ABSTRACT

The rapid growth of chemical and process industries has intensified the demand for efficient, cost effective, and environmentally sustainable catalytic systems. Conventional catalyst synthesis routes often involve toxic reagents, high energy consumption, and limited recyclability, creating both environmental and economic challenges. This research article presents a comprehensive techno-chemical study on the green synthesis of metal oxide nanocatalysts using plant-based reducing and stabilizing agents, and evaluates their chemical performance, scalability, and techno-economic feasibility for industrial deployment. The study integrates experimental synthesis, physicochemical characterization, catalytic performance analysis, life-cycle considerations, and cost modeling. Results demonstrate that green-synthesized nanocatalysts exhibit comparable or superior catalytic activity to conventionally synthesized counterparts while significantly reducing environmental footprint and production costs. The findings support the viability of green nanocatalysis as a sustainable alternative for modern chemical manufacturing.
