| 中文摘要 | solar energy is the primary source for clean and renewable energy alternative. the concerns about the depletion of fossil fuel reserves and the pollution caused by continuously increasing energy demands make solar fuels an attractive energy source. this lecture discusses the key issues concerning the photocatalytic materials designating and preparation for the productions of solar fuels, mainly photocatalytic hydrogen production and photocatalytic reduction of co2 utilizing solar energy, focusing on the fundamental understanding of photocatalysis and photochemical reactions on semiconductor-based photocatalysts. semiconductor materials are believed to be the most promising components for photocatalysts, so the discovery and synthesis of novel semiconductor materials are crucial for the development of advanced photocatalysts. to convert solar energy efficiently to chemical energy, much attention has been paid to reducing charge recombination and improving solar energy conversion efficiency. our recent results demonstrate that the formation of surface phase junction and hetero-junction on semiconductor catalysts can significantly enhance the activity in photocatalytic hydrogen production. by mimicking the photosynthesis, loading spatially separated dual cocatalysts for oxidation and reduction on semiconductor nanoparticles can effectively avoid the charge recombination and consequently increase the photocatalytic activity. a recent progress made in photocatalytic hydrogen production shows that a quantum yield up to 93% can be achieved for pt-pds/cds catalysts where the dual co-catalysts, pt and pds nanoparticles act as reduction and oxidation co-catalysts respectively. the finely designing and preparation of junctions at atomic and nano-scale together with spatially separated dual co-catalysts findings is a strategy to develop highly active photocatalysts for solar fuel production. |
