Establishing an ideal photocatalytic system with efficient reactive oxygen species (ROS) generation has been regarded as the linchpin for realizing efficient nitric oxide (NO) removal and unveiling the ROS-mediated mechanism. In this work, a novel oxygen-deficient 0D/1D Bi3.64Mo0.36O6.55/Bi2MoO6 heterojunctions (BMO-12-H) were successfully synthesized under the enlightenment of clarified crystal growth mechanism of bismuth molybdates. Because of the synergies between defect-engineering and heterojunction-construction, BMO-12-H demonstrated improved photoelectrochem. properties and O2 adsorption capacity, which in turn facilitated the ROS generation and conversion. The enhancement of •O-2 and 1O2 endowed BMO-12-H with strengthened NO removal efficiency (59%) with a rate constant of 12.6*10-2 min-1. A conceivable NO removal mechanism dominated by •O-2 and 1O2 was proposed and verified based on the theor. calculations and in-situ IR spectroscopy tests, where hazardous NO was oxidized following two different exothermic pathways: the •O-2-induced NO → NO-3 process and the 1O2-induced NO → NO2 → NO-3 process. This work offers a basic guideline for accelerating ROS generation by integrating defect-engineering and heterojunction-construction, and provides new insights into the mechanism of efficient NO removal dominated by •O-2 and 1O2.
