Semiconducting Graphene-Based Materials as Efficient Solar Active Catalysts for Conducive Environment

Graphene-based materials with semiconducting properties (SGBM) have ignited a range of redox reactions to facilitate diverse photocatalytic processes. These materials have drawn significant attention from the scientific community due to their unique structural characteristics, such as extensive surface area, strong adsorption capacity, remarkable thermal, mechanical and chemical stability, high electron mobility and lightweight nature. They hold great potential for expanding their role in several photocatalytic applications including dye removal, CO2 reduction, hydrogen production and the breakdown of pharmaceutical waste. SGBMs overcome the limitations of traditional photocatalysts by acting as co-catalysts and forming heterojunctions with oxides, sulphides, phosphorus and selenides, offering sustainable solutions to address energy and environmental challenges. This book chapter introduces innovative concepts for addressing environmental sustainability issues and underscores the utility of graphene-based heterostructure catalysts in diverse solar energy-driven fields.
