Photobiocatalysis is a novel concept that aims at merging the features from photocatalysis and enzymatic catalysis. The process of photocatalysis involves the degradation of contaminants in water and air. It has also shown promising application in solar energy. However, many photocatalytic processes have low efficiency as compared to other enzymatic processes. Therefore, to improve the performance of such photocatalytic processes, a promising photobiocatalysis approach shows a great promise to enhance the effectiveness of the photocatalytic system. The combination of photocatalysis and biocatalysis technologies is an alternative to develop environmentally benign process for the synthesis of renewable chemicals. In photobiocatalysis, the semiconductor coupled with the enzyme which regularly needs a natural compound and a relay transferring charge carriers from the semiconductor. The enzyme diminution mediated by NAD+/NADH along with an electron relay utilized the conductivity band electrons of excited semiconductors for photobiocatalysis. The photosynthetic organisms are the natural source for photobiocatalysis.

The present write-up discusses the working mechanism and applications of the current photocatalytic system such as metal oxide photocatalyst and graphene-based photocatalyst. Advances in enzyme-mediated photocatalysis are particularly discussed. The critical factors to control the photobiocatalytic process and key enzymes involved in deciphering the reaction mechanism of photobiocatalysis are critically discussed. Cofactor vs mediator medicated photobiocatalysis is also discussed.
