Synergistic Effect of Sr‐O Divacancy and Exposing Facets in SrTiO ₃ Micro/Nano Particle: Accelerating Exciton Formation and Splitting, Highly Efficient Co ²⁺ Photooxidation (Small 44/2022)

Co2+ Photooxidation Multiple crystal surface exposure gives SrTiO3 micro/nano crystal better photocatalytic performance. In addition to the exposed crystal surface, the vacancy is vitally important. In article number 2202659, Li-zhu Wu, Dongping Duan, and co-workers investigate the dynamic formation mechanism of atomic vacancies of SrTiO3 crystal deeply, and more importantly, the Sr-O di-vacancies play an important role in the transition of exciton and free carriers. The photocatalytic reaction of Co2+ is used as the probe reaction, and the unique SrTiO3 possesses a high photooxidation efficiency of Co2+ resulting from more free carriers.
