Photocatalysis is a facile and sustainable approach for energy conversion environmental remediation by generating solar fuels from water splitting. Due to their two-dimensional (2D) layered structure excellent physicochemical properties, molybdenum disulfide (MoS2) has been effectively utilized in photocatalytic H2 evolution reaction (HER) CO2 reduction. The efficiency of MoS2 greatly depends on the active edge sites present structure. Modifications like reducing layer numbers, creating defective structures, adopting different morphologies produce more unsaturated S atoms as sites. Hence, acts cocatalyst nanocomposites/heterojunctions facilitate photogenerated electron transfer.
