The elaborate thermodynamic reaction pathways on Ga2O3-decorated and -defective surfaces during photothermal catalytic CO2 conversion with H2O have been established. The basic site generated by Ga2O3 decoration on an anatase TiO2 (101) surface enhances the selective adsorption of CO2, and also balances VO formation and CO2 reduction activity. Surface-defect VO promotes the reaction thermodynamics but tends to be consumed; Ga2O3 helps to keep VO active. Ga2O3 and VO together further decrease the energy barrier of the rate-determining step, thereby promoting C1 production. More information can be found in the Research Article by Y.-W. Zhang et al. (DOI: 10.1002/chem.202104490).

封面专题:在氧化镓装饰和缺陷表面上与 H2O 进行光热催化 CO2 转化的详细反应途径(Chem. Eur. J. 24/2022)

已经建立了在用H 2 O 进行光热催化CO 2转化过程中Ga 2 O 3修饰和缺陷表面上复杂的热力学反应途径。Ga 2 O 3修饰在锐钛矿TiO 2 (101)表面上产生的碱性位点增强了对CO 2的选择性吸附,也平衡了V O的形成和CO 2的还原活性。表面缺陷 V O促进反应热力学,但往往被消耗;Ga 2 O 3有助于保持VO活性。镓2 O 3和V O一起进一步降低了限速步骤的能垒,从而促进了C1的产生。更多信息可以在 Y.-W 的研究文章中找到。张等人。(DOI:10.1002/chem.202104490)。
