Abstract Green catalysts, with their beneficial ecological qualities, have revolutionized chemical processes and become key players in sustainable development. This abstract offers an overview of how green catalysts support sustainability in a range of sectors. The move toward more resource and environmentally conscious catalytic processes is represented by the use of green catalysts. The many approaches used in green catalysis such as photocatalysis, biocatalysis, and nanocatalysis are examined in this review. Each of these approaches offers a special benefit to sustainable chemistry. High surface area and reactivity nanocatalysts hold potential for improving catalytic efficiency with the least amount of negative environmental effects. Green chemistry concepts are in line with biocatalysis, which uses naturally occurring catalysts such as enzymes to provide high selectivity and gentle reaction conditions. Utilizing sun energy, photocatalysis offers a sustainable method of achieving many kinds of chemical reactions. Green catalysis has consequences for pharmaceutical synthesis as well. Here, new and sustainable catalytic methodology can be designed to eliminate waste, expedite operations, and ensure strict regulatory compliance. The review deliver deeper into the cutting-edge developments and uncharted territory in green catalysis, with a focus on photocatalysis, biocatalysis, and nanocatalysis and its uses in sustainable energy conversion and pharmaceuticals. Green catalysts in pharmacy promise sustainable medication manufacturing in the future, along with regulatory compliance, innovation, and advancement in the field of green chemistry. Green catalysts are emerging as change-catalysts, guiding chemical processes towards a more sustainable and environmentally friendly future as industries realize the necessity of environmentally responsible practices.

Key words: green chemistry, green catalysis, nanocatalyst, Environmentally sustainable.
