제목 The Role of Co-catalysts and Surface Junctions Played in Photocatalytic Hydrogen Production
초록 In this lecture, we present our recent study on photocatalytic hydrogen production by spectroscopy, such as UV Raman, time-resolved FT-IR and Fluorescence spectroscopy. The activity of photocatalytic H2 production can be significantly enhanced when small amount of MoS2 is loaded on CdS as co-catalyst. The junction formed between MoS2 and CdS and the excellent H2 activation property of MoS2 are supposed to be responsible for the enhanced photocatalytic activity of MoS2/CdS. In addition, PtPdS/CdS catalyst demonstrates the possibility of realizing visible-light-responsive photocatalytic hydrogen production with a QE approaching the level of natural photosynthesis.[1] The strategy to achieve high QE by co-loading suitable dual cocatalysts, especially those functioning as oxidation and reduction cocatalysts, respectively, will be of considerable importance in the design and preparation of highly active photocatalysts for solar energy conversion.
