چکیده

Single-atom catalysts have recently received much scientific attraction as sustainable catalysts due to their greater activity and selectivity arising from the uniform distribution, electronic properties, and quantum mechanical interactions at the nanoscale of single atoms coupled with interactions at the metal-support interfaces. Carbon-based materials are an excellent support material for single-atom catalysts owing to their inherent properties such as adjustable pore size, high surface area to volume ratio, and ease of surface functionalization. The interactions at the single atom-carbon support interfaces give rise to the extraordinary catalytic activity in carbon-based single metal catalysts thus opening doors for a wide range of sustainable applications. This review focuses on the evolution of carbon-based single-atom catalysis covering different types of carbon substrates, usage of different single atoms with special attention to transition metals, and its wide range of applications including photocatalysis, organic catalysis, and electrocatalysis followed by the future perspectives on carbon-based single-atom catalysts.
