摘　　要：Catalysis,as a core technology in the chemical industry,plays a pivotal role in numerous fields,including energy,environmental science,and materials engineering.Platinum(Pt),a ubiquitous and indispensable catalyst,has been extensively employed in diverse applications,including industrial chemical transformations and automotive emission control systems[1].However,it was believed to suffer from deactivation under severe operating conditions,particularly in high-temperature and oxidizing environments.Conventional concept suggests that platinum oxides,decompose or sublimate at elevated temperatures,typically above 700 K[2].Consequently,researchers frequently employ encapsulation techniques for metal particles,utilizing materials such as mesoporous silica[3],zeolites[4],two-dimensional(2D)layered materials[5],and various other protective structures.This approach necessitates a delicate balance between activity and stability,often resulting in enhanced stability at the expense of catalytic efficiency.
