Green Chemistry and Catalysis: Innovations toward a cleaner and Sustainable World

Abstract

Green chemistry represents a transformative shift in chemical science, promoting processes and practicesthatprioritizesustainability,wasteminimizat ion,andreducedenvironmentalimpact.The central principles of green chemistry emphasize the reduction or elimination of hazardous substances, the design of safer chemicals and products, and a commitment to efficient use of resources.Acriticalcomponent withinthis frameworkiscatalysis, ascatalysts facilitatechemical transformations by enhancing reaction rates, increasing atom economy, and minimizing waste without beingconsumed inthereaction.Thisreviewdelvesintothepivotalroleof greencatalysts in advancing sustainable chemistry, categorizing them into various types, examining their mechanistic aspects, exploring sustainable catalyst design, and highlighting keyapplications and challenges. Mechanistically, green catalysts improve efficiency by lowering activation energy, enhancing reaction kinetics, and allowing reactions to proceed under milder conditions. Factors suchassurfacearea,poresize,andelectronicproperties significantlyinfluencecatalyticefficiency and selectivity, underscoring the importance of tailoring catalysts to specific applications. Sustainable catalyst design emphasizes recyclability, durability, and environmentally friendly synthesis.
