Photocatalytic overall pure-water splitting using the 2D heterostructures of BP/BiVO4 without any sacrificial agents under visible light irradiation.
Researchers combined 2 2D materials – black phosphorus and bismuth vanadate – to form a biologically inspired water-splitting catalyst. Normal sunlight could drive the reactions and careful design of the catalyst enabled the expected ratio of hydrogen and oxygen production. Burning hydrogen produces harmless water with the potential to eliminate CO2 emissions and their environmental burden. In pursuit of technologies that could lead to a breakthrough in achieving a hydrogen economy, a key issue is making hydrogen cheaply...
