Selective photocatalytic oxidation of benzyl alcohol into benzaldehyde with high selectivity and conversion ratio over Bi4O5Br2 nanoflakes under blue LED irradiation
Bi4O5Br2 nanoflakes with a thickness of approximately 5 nm are synthesized by a rapid and energy saving microwave route. Bi4O5Br2 nanoflakes show excellent conversion efficiency (>99%) and selectivity (>99%) toward photocatalytic oxidation of BA into BAD under blue LED. A possible mechanism of selective photocatalytic oxidation with high selectivity and conversion ratio is proposed based on experimental results and DFT calculations.
