Key Points

  • The study aims to enhance charge separation in Cs3Sb2Br9 photocatalyst using a WO3 semiconductor.
  • Integrated Cs3Sb2Br9 with WO3 to form a heterojunction
  • Investigated photocatalytic activity for green-light-driven oxidation of benzyl alcohol
  • Analyzed charge recombination processes
  • Cs3Sb2Br9/WO3 heterojunction significantly suppressed charge recombination, improving photocatalytic efficiency.
  • Enhanced oxidation rates of benzyl alcohol under green light were observed with the heterojunction setup.

Abstract

Herein, we report an effective strategy to suppress charge recombination in Cs3Sb2Br9 (CSB) photocatalyst by integrating it with electron storing semiconductor, WO3. The resulting Cs3Sb2Br9/WO3 (CSBW) heterojunction is investigated for...
