High-Performance Photocatalytic H Production Using a Binary Cu/TiO/SrTiO Heterojunction.

Cu/TiO/SrTiO hybrid structures have been synthesized by the simple impregnation method from Cu/TiO and SrTiO systems. The structural and surface characterization stated that Cu/TiO/SrTiO composites form an effective covering of SrTiO by Cu/TiO. The heterostructured catalysts lead to an outstanding improved photoactivity for hydrogen production from methanol photoreforming that would be related with the efficient separation of charge pairs favored by the Cu/TiO/SrTiO heterojunction.
