Metal-support active interfaces provide unique sites that enhance catalytic oxidation reactions. However, designing a catalyst that simultaneously promote both benzene ring cleavage and C−H bond scission remains a challenge. Herein, porous SiO₂ derived from waste rice husk was used to disperse CeO₂ nanoparticles, onto which Pt nanoparticles were deposited via ethylene glycol reflux reduction combined with steam redispersion to prepare a Pt/CeO₂/SiO₂ catalyst with abundant Pt−O−Ce active interfaces. Characterization and experimental results show that well-dispersed CeO₂ and Pt nanoparticles increase oxygen vacancy concentration and Pt–O–Ce interfaces, thereby enhancing oxygen spillover from CeO₂ to Pt and promoting styrene oxidation. The Pt–O–Ce interface accelerates the rate-determining C−H bond cleavage in benzaldehyde during styrene oxidation. Pt/CeO₂/SiO₂-H₂O catalyst with abundant oxygen vacancies and Pt–O–Ce interfaces achieves excellent catalytic performance (T₉₀ = 222 ℃, WHSV = 120,000 mL h⁻¹ g⁻¹). Moreover, it demonstrates superior thermal stability over 40 h and water-resistance against 10 vol% H₂O, highlighting its industrial potential. This study offers a strategy for constructing supported catalysts with tailored active interfaces and high stability.
