Mini-Review on Catalytic Hydrogen Evolution from Porphyrin-Graphene Structures.

Porphyrin-based derivatives have been extensively investigated in photocatalytic, electrocatalytic, and photoelectrocatalytic H production systems as both photosensitizers and catalysts. Recently, their combination with two-dimensional materials, such as graphene oxide, reduced graphene oxide, and graphene quantum dots, has attracted significant attention for hydrogen evolution due to the advanced electronic properties, good stability, and low-cost fabrication of these materials. This mini-review summarizes the recent developments concerning the application of porphyrin-graphene ensembles in catalytic H generation. Current challenges concerning this application are discussed, and future perspectives are also proposed.
