AI Technical Summary
In existing technologies, the degree of surface functionalization of carbon materials treated by ozone is uncontrollable and the equipment is complex. The preparation process of supported catalysts is cumbersome and polluting, making it difficult to achieve large-scale production and uniform loading.
The surface of carbon materials is modified by atmospheric ball milling. Combining pulverization, surface modification and loading processes, ozone is used to react gently with carbon materials in the ball mill jar to form a loaded metal precursor salt solution under negative pressure, which simplifies the preparation process.
The proportion of oxygen-containing functional groups on the surface of carbon materials is increased, achieving uniform dispersion and pore loading of active components, simplifying the preparation process, reducing costs, and making it suitable for industrial applications.
