Dynamic Reconfiguration and Local Polarization of NiFe-Layered Double Hydroxide-Bi₂MoO_{6- x} Heterojunction for Enhancing Piezo-Photocatalytic Nitrogen Oxidation to Nitric Acid.

ABSTRACT: Constructing heterojunctions with vacancies has garnered substantial attention in the field of piezo-photocatalysis. However, the presence of interfacial vacancies can serve as charge-trapping sites, leading to the localization of electrons and hindering interfacial charge transfer. Herein, dual oxygen vacancies in the NiFe-layered double hydroxide and Bi₂MoO_{6- x} induced interfacial bonds have been designed for the piezo-photocatalytic N₂ oxidation to NO₃ ^-. Fortunately, it achieves sensational nitric acid production rates (7.23 mg g^-1 h^-1) in the absence of cocatalysts and sacrificial agents, which is 6.03 times of pure Bi₂MoO₆ that under ultrasound and light illumination.
