Synergetic effects of Bi5+ and oxygen vacancies in Bismuth(V)-rich Bi4O7 nanosheets for enhanced near-infrared light driven photocatalysis

• The Bi 4 O 7 nanosheets were fabricated as an NIR light responsive photocatalyst. • Synergetic effects of Bi 5+ and oxygen vacancies enhanced the NIR light driven photocatalysis. • The photocatalytic mechanism was unveiled based on the experiments and DFT calculations. The appropriate energy level position of photocatalysts dominates the photocatalytic redox reaction and utilization efficiency of solar energy for wastewater treatment. Herein,...
