Photocatalytic reactive oxygen species (ROS) evolution with Bi5O7I still suffers from sluggish charge carrier dynamics and limited light absorption. Herein, abundant vacancies (OVs) were introduced into the microflower-like Bi5O7I, its ROS generation toward organic dye degradation under synergistic effect of visible ultrasound irradiation was investigated. Benefiting broadened visible-light absorption range, stronger piezoresponse, higher transport efficiency in OV-enriched (2-PEG-Bi5O7I), both photocatalytic piezocatalytic degradations improved. More importantly, piezo-photocatalytic performance greater than sum corresponding photocatalysis piezocatalysis, indicating a strong coupling effect. In addition, yield •O2– 2-PEG-Bi5O7I 1.5 times that it also 4.3 3.1 single respectively. Interestingly, no noticeable •OH detected case irradiation, while yields 3.6 5.3 μmol g–1 h–1, respectively, surpassing pristine as well. This work advances between piezocatalysis new strategy for efficient discloses positive role improving multiresponsive catalysis.
