Efficient benzaldehyde photosynthesis coupling photocatalytic hydrogen evolution
文献摘要：
Photosynthesis of organic compounds in coupling with promoted hydrogen evolution under mild condi-tions of light irradiation is considered as one of the most efficient and promising approach to obtain high purity hydrogen and value-added chemicals concurrently by utilizing green solar energy.Here,we report the synthesis of NiS nanoparticle-modified CdS nanorod composites(NiS/CdS)as an efficient bifunctional catalyst for the highly selective photocatalytic synthesis of high-value-added product benzaldehyde(BAD)from aqueous solution of benzyl alcohol(BA)under oxygen-free conditions,in accompanying with the efficient hydrogen evolution.The synergetic catalytic effect between NiS and CdS is proposed to play an important role in elevating the photo-redox performance.The composition-optimized 30％NiS/CdS catalyst affords an extraordinarily high H2 generation rate of 207.8 pmol h-1 and a simultaneous BAD generation rate of 163.8 pmol h-1 under visible light irradiation,which are respectively 139 and 950 times higher than those of CdS without NiS modification.To our knowledge,these are the highest pho-tocatalytic production rates of both H2 and aldehyde ever reported on the concurrent photocatalytic of aldehyde synthesis and hydrogen evolution in green aqueous solution.This work provides a highly effi-cient photosynthesis strategy for the concurrent productions of high-value-added fine chemicals and hydrogen.
