Band Gap Engineering in Phosphorene for Solar-to-Chemical Energy Conversion

Two-dimensional (2D) semiconductors are an emerging platform for solar energy conversion because of their attractive properties: (i) thickness-tunable band gaps that can be varied across the solar spectrum; (ii) their surface intrinsically lacks surface states that would facilitate recombination; (iii) bulk recombination is not possible in atomically thin materials. So far, however, these features of 2D materials have not been exploited in solar to chemical energy conversion. We demonstrate that a quantum confined 2D semiconductor, 2D black phosphorus (BP), can be used to convert solar to chemical energy.
