Abstract

Abstract

En 中文
• Four Pt/CeO2 with varied Pt-CeO2 interaction were constructed to probe metal-support effects. • A stronger Pt-CeO2 interaction enhanced the oxidation activity of CVOCs. • Pt-CeO2 interactions promoted electron transfer from Pt to CeO2 via Pt-O-Ce interface. • In-situ and DFT studies revealed electronic perturbation sustained a dynamic Pt0/Pt2+ cycle. • This cycle enhanced DCM adsorption and O2 activation, boosting catalytic activity and stability.
