Photocatalytic hydrogen production

This review focuses on the efficiency of different nanomaterials used in photocatalytic hydrogen production. Some 200 articles were reviewed for photocatalytic hydrogen production (liquid and gas phase) in a random review of photocatalysts for both water and H2S splitting. The photocatalytic reactors used for both liquid- and gas-phase hydrogen production are also discussed. Among the photocatalysts used, nanosized photocatalyts have a much greater surface area and thus give a better hydrogen yield than microsized photocatalysts.
