The increasing energy demand and depletion of fossil fuels are leading to a rise in atmospheric CO2, causing global warming. Visible light-driven semiconductor photocatalysis is an emerging discipline to reduce CO2 into value-added chemicals. single Atom Catalysts (sACs) are new generation catalysts that use isolated metal atoms anchored on a support catalyst, coordinated with nitrogen, sulfur, and oxygen-like atoms. These sACs have excellent catalytic properties, enhancing substrate conversion rates and controlling adsorption behavior of reactive intermediates. sACs offer an effective approach to create inexpensive catalysts for various applications, such as organic transformations, electrocatalysis, and photocatalysis. However, isolated sACs may aggregate easily due to their high surface free energy, necessitating their stabilization by chemical bonds or confined space. g-C3N₄ has emerged as a promising support for sAC development due to its high porosity, functional adaptability, structural tailorability, and abundance of potent anchoring sites. These photocatalysts are used to investigate their photocatalytic performance towards CO2 photoreduction reaction.
