摘要

开发高效、通用的助催化剂对光催化CO2 / H2O转化具有重要意义。通过将Ga(OH)3负载到光催化剂表面和原位添加Na2CrO4的共催化偶联，成功地促进了该反应中CO的演化。该策略对一系列基于Ta和ga的光催化剂具有良好的通用性。Ga(OH)3的修饰在光催化剂表面产生CO的活性位点。当满足两个条件时，原位添加Na2CrO4可以提高CO的析出活性：(1)使用合适的助催化剂形成CO析出活性位点；(2)光催化剂表面被氢氧化物离子充分淬灭。

Coupling Ga(OH)3 and chromate as a universal cocatalyst for CO2 photoreduction by H2O

Development of effective and universal cocatalysts are very important to the photocatalytic conversion of CO₂ by H₂O. Herein, CO evolution from this reaction was successfully promoted by co-catalytic coupling featuring Ga(OH)₃ loading onto photocatalyst surfaces and in situ addition of Na₂CrO₄. This strategy exhibited excellent universality for a series of Ta- and Ga-based photocatalysts. Modifications of Ga(OH)₃ created active sites for CO production on the photocatalyst surfaces. The in situ addition of Na₂CrO₄ improved CO evolution activity when two factors were satisfied: (1) active sites for CO evolution were created using the proper cocatalysts and (2) the photocatalyst surfaces were sufficiently quenched by hydroxide ions.

期刊介绍： Catalysis Today focuses on the rapid publication of original invited papers devoted to currently important topics in catalysis and related subjects. The journal only publishes special issues (Proposing a Catalysis Today Special Issue), each of which is supervised by Guest Editors who recruit individual papers and oversee the peer review process. Catalysis Today offers researchers in the field of catalysis in-depth overviews of topical issues. Both fundamental and applied aspects of catalysis are covered. Subjects such as catalysis of immobilized organometallic and biocatalytic systems are welcome. Subjects related to catalysis such as experimental techniques, adsorption, process technology, synthesis, in situ characterization, computational, theoretical modeling, imaging and others are included if there is a clear relationship to catalysis.
