Abstract
The properties and mechanism research of nanocatalysts were reviewed.In terms of performance evaluation,reactivity test,selective evaluation and surface characteristic analysis are widely used.In terms of catalytic mechanism,kinetic studies,intermediate detection and active site studies have revealed the mechanism of catalyst action.The properties and mechanisms of nano-metal,oxide and carbon catalysts in different reactions were demonstrated.At the same time,challenges and prospects were discussed,including the feasibility and sustainability of industrial production,the stability and longevity of catalysts,the improvement of large-scale preparation methods,as well as application prospects and development directions.The properties and mechanism of nanocatalysts were summarized,providing important reference for further research and application.
