Highly stable and durable ZnIn2S4 nanosheets wrapped oxygen deficient blue TiO2(B) catalyst for selective CO2 photoreduction into CO and CH4

Fabrication of site activated and synergistic double vacancy ZnIn2S4 for highly efficient bifunctional photocatalysis: nitrogen reduction and oxidative degradation

“…25 However, like most other semiconducting materials, the vertical transportation of hot carriers results in fast recombination in perfect ZnIn 2 S 4 . 28–32 Meanwhile many methods such as the construction of heterojunctions, crystal surface engineering, compositional regulations, and defect engineering have lately shown great promise in overcoming these intrinsic barriers in photocatalysis. In the case of ZnIn 2 S 4 -based photocatalysts, the creation of Zn 33 and S 34,35 vacancies has been achieved via defect engineering for regulated band structures and hot carrier dynamics.…”

Enhanced photocatalytic CO2 reduction by controlled oxygen vacancy generation and co-constructed heterojunction strategy for Pd/CeO2

“…Extensive research has been conducted to enhance the efficiency and stability of photocatalysts. 4–6 Nevertheless, the photocatalytic activity of CO 2 reduction is currently constrained by the considerable activation energy required for carbon dioxide and the sluggish kinetics associated with specific electron and proton transfer processes. 7 Thus, it is a feasible prospect to find a reliable strategy to enhance the separation efficiency of photogenerated carriers for CO 2 -activated photocatalysts.…”
