Significantly, the piezo-photocatalytic process leads to the highest ORR performance of the Bi4NbO8Br nanoplates, exhibiting •O2, H2O2, and •OH evolution rates of 98.7, 792, and 33.2 µmol g−1 h−1, respectively. The formation of a polarized electric field and band bending allows directional separation of charge carriers, promoting the catalytic activity. Furthermore, the reductive active sites are found enriched on all the facets in the piezo–photocatalytic process, also contributing to the ORR. By piezo–photodeposition of Pt to artificially plant reductive reactive sites, the Bi4NbO8Br plates demonstrate largely enhanced photocatalytic H2 production activity with a rate of 203.7 µmol g−1 h−1. The present work advances piezo–photocatalysis as a new route for ROS generation, but also discloses the potential of piezo–photocatalytic active sites enriching for H2 evolution.]]> Thu 01 Dec 2022 10:40:44 AEDT ]]>
