Photocatalytic ability of visible-light-responsive hybrid ZrO₂ particles

Abstract

The interfacial charge transfer (ICT) complex formation between zirconium dioxide (ZrO2), material absorbing below 250 nm, and 5-aminosalicylic acid (5-ASA) lead to the formation of visible-light-absorbing inorganic-organic hybrid. The free...

Recent Progress in Photocatalytic Reduction of CO2 by ZnIn2S4‐based Heterostructures

“…Among many photocatalysts, ZnIn 2 S 4 , as a ternary metal‐sulfur compound semiconductor catalyst with a typical layer structure, has a narrower band gap compared with traditional oxide photocatalysts such as TiO 2 , [2–3] ZnO, [4–7] ZrO 2 , [8–11] etc. Compared with binary metal‐sulfur semiconductor photocatalysts such as CdS, [12–14] CuS, [15–19] and ZnS, [20–23] ZnIn 2 S 4 is greener in the photocatalytic reaction process without generating toxic ions and more straightforward to prepare compared with other ternary metal‐sulfur compounds such as ZnCdS, [24–27] Zn 3 In 2 S 6 , [28–31] etc., while attracting the attention of many related workers by its unique photoelectric properties and catalytic characteristics.…”
