Sustainable chemistry is focused with the creation of products that decrease the use and manufacture of environmentally harmful hazardous chemicals. Sustainable Chemistry is based on Paul Anastas and John Werner’s 12 Principles of Green Chemistry, which were published in the 1990s and lay out a roadmap for long-term growth. The most essential of them is the use of catalysts to enhance atom economy and reaction yield. Catalysts are the building blocks of Green Chemistry, and there is a global search for novel catalysts. A chemical reaction’s atom economy is a theoretical measure of the amount of starting material transformed into the desired product and is a reliable predictor of the reaction’s greenness. As a result, a 100 percent atom economy equals zero waste. Green catalysts are recommended for several reasons: 1) improved atom economy, 2) reduced waste generation, 3) environmentally friendly products and emissions, and 4) reusability.

Biocatalysts, enzyme catalysts, nanocatalysts, and phase transfer catalysts are some examples of extensively used Green catalysts.

Toxic metal ions, such as Cr(VI), have been utilised to accelerate organic processes on a wide scale. As part of a green initiative, attempts have been undertaken to catalyse processes with less dangerous transition metal ions. The indiscriminate use of natural resources produces hazardous waste, resulting in environmental damage. Green Chemistry methods such as the use of catalysts assist to preserve precious resources by ensuring atom economy.

This article discusses the goals and key characteristics of Sustainable Chemistry, as well as the critical role catalysts play in sustainable development. The many types of catalysts, with a focus on green catalysts, as well as the catalysis mechanism, are presented with pertinent examples.
