Photocatalysts with atomic dimensions demonstrate superior performance in photocatalytic applications due to their large surface-to-volume ratio, enormous surface active sites, and superior light harvesting ability. The single-unit-cell thickness reduces interlayer charge transfer resistance, facilitating rapid transfer of electrons and holes from the interior to the surface.
Photocatalysts with atomic dimensions exhibit superior performance in photocatalytic applications owing to their large surface-to-volume ratio, enormous surface active sites, and superior light harvesting ability. The single-unit-cell thickness reduces interlayer charge transfer resistance, facilitating the rapid transfer of electrons and holes from the interior to the surface. This review aims to provide a comprehensive discussion on the fundamentals of photocatalysis and the advancements achieved from the evolution of photocatalysts from their bulk-counterpart to atomic dimensions. State-of-the-art techniques in designing and modifying atomically thin photocatalysts, such as defect engineering, impurity doping, facet engineering, and atomic-scale heterojunction construction, for diverse photocatalytic applications will be comprehensively elucidated.
