Roles of Cocatalysts in Photocatalysis and Photoelectrocatalysis
  English.dicp.cas.cn    Posted:2013-05-13

In recent years, studies on development of photocatalysts and photoelectrochemical catalysts basing on junctions and cocatalysts and conducted by Prof. Can Li’s team in the State Key Laboratory of Catalysis and in the Solar Energy Division of Dalian National Laboratory for Clean Energy have been attracting great attentions in the research community of solar energy conversion. And their review paper entitled “Roles of Cocatalysts in Photocatalysis and Photoelectrocatalysis” has been recently accepted for publication in Accounts of Chemical Research (Jinhui Yang, Donge Wang, Hongxian Han, and Can LiAcc. Chem. Res., Article ASAPDOI: 10.1021/ar300227ehttp://pubs.acs.org/doi/abs/10.1021/ar300227e ).

Water splitting is considered as the “holy grail of science”. But being an energetically uphill and multi-electron transfer process, it is an extremely difficult reaction to achieve, so it is also called “a Goldbach Guess type research in science”. It has been proved by more than 40 years’ research that single component photocatalysts cannot efficiently split water. In order to effectively split water, it is necessary to assemble multi-component photocatalytic systems. Prof. Can Li’s team has proposed an approach to develop junction and cocatalyst based photocatalytic systems for water splitting, and accomplished a series of research achievements in recent yearsNature Commun., 4, 1432, 2013; Angew. Chem. Int. Ed., 51, 13089, 2012; J. Catal., 290, 151, 2012; J. Phys. Chem. C, 116, 5082, 2012;ChemSusChem, 5, 849, 2012 Energy Environ. Sci., 5, 6400, 2012;  J. Catal., 281, 318, 2011; J. Phys. Chem.
