| contents | Photothermal Catalytic CO 2 Dissociation Over Nb 2 O 5 –Nb 2 CT x Schottky Heterostructures Yuqian Deng Xingyu Li Zhouyan Zhao Qingqing Jiang Juncheng Hu Advanced Synthesis & Catalysis Solar‐driven CO 2 dissociation reaction via a two‐step thermochemical cycle is a promising option, but it requires extremely high reaction temperatures (>1000°C). Herein, we designed Nb 2 O 5 –Nb 2 CT x Schottky heterostructures that could achieve photoinduced thermochemical CO 2 dissociation reaction at 300°C. Under light irradiation, the CO production rate of Nb 2 O 5 –Nb 2 CT x reaches to 70.1 μmol g −1 h −1 , which is three times higher than that of pristine Nb 2 O 5 . The high activity arose from the superior photothermal conversion efficiency of Nb 2 CT x , fast charge separation and transfer kinetics from the Schottky heterostructures, increased surface CO 2 adsorption sites from photoinduced oxygen vacancies, and efficient redox cycling ability. This work presents a feasible strategy to fabricate photothermal synergistic catalysts which could achieve stable CO 2 dissociation performance at mild reaction temperature. 10.1002/adsc.70310 http://onlinelibrary.wiley.com/termsAndConditions#vor |
