Innovative Z-scheme photocatalysis for solar-to-chemical energy conversion

The amount of solar energy reaching earth is about 10 000 times larger than our current global energy consumption. The direct photocatalytic solar-to-chemical energy conversion is a promising approach as it overcomes the variable solar availability. In the last decade, Z-scheme photocatalysts (PCs) that mimic natural photosynthesis, have been explored as they combine the advantages of small band gaps and strong solar response, with improved redox abilities. In this project, metal halide perovskites (MHPs) with narrow anddirect band gap will be coupled to Bi-based PCs with strongly oxidizing power to construct a direct Z-scheme PC for artificial solar-to-chemical energy conversion. By exploiting the host laboratories expertise in material synthesis and through in depth physical and opto-electronic characterization, the two PCs will be optimized to improve the efficiency of the final Z-scheme PC.
