Abstract

A novel bismuth chromate material (Cr₂Bi₃O₁₁) was synthesized by a direct mixing method with higher photocatalytic activity in both organic pollutant detoxification and oxygen evolution. Cr₂Bi₃O₁₁ with a band gap of 2.20 eV could be activated by photons with a wavelength below 561 nm. This work not only provides an approach for the controllable synthesis of Cr₂Bi₃O₁₁, but also experimentally and theoretically shows its excellence and potential when applied in photocatalysis.
