Dynamic Reconfiguration and Local Polarization of NiFe-Layered Double Hydroxide-BiMoO Heterojunction for Enhancing Piezo-Photocatalytic Nitrogen Oxidation to Nitric Acid.

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 BiMoO induced interfacial bonds have been designed for the piezo-photocatalytic N oxidation to NO .

Electronic configuration inversion in CdInS for efficient photocatalytic hydrogen peroxide generation coupled with selective benzylamine oxidation.

Vacancies engineering has sparked a huge interest in enhancing photocatalytic activity, but monovacancy simultaneously conducts as either electron or hole acceptor and redox reaction, worsening charge transfer and catalytic performance. Here, the concept of electronic inversion has been proposed through the simultaneous introduction of surface oxygen and S vacancies in CdInS (OS-CIS). Consequently, under mild conditions, the well-designed OS-CIS-200 demonstrated a strong rate of N-benzylidenebenzylamine production (2972.
