Summary: Supports can regulate the atomic geometry and electronic structures of active sites at the interface, thus affecting the catalytic activity and selectivity of nanoparticles. In this study, we constructed the Co3O4/TiO2 interface to enhance the catalytic decomposition of ammonium perchlorate (AP). Experimental and theoretical studies revealed that Co3O4 nanoparticles can strongly anchor onto TiO2 supports with charge transfer, leading to enhanced NH3 adsorption through hydrogen bonds at the interface. These findings provide new insights into the promotion effects of the nanoparticle/support system on the AP decomposition process and inspire efficient catalyst design.
