Supported carbon catalyst preparation method

The invention provides a supported carbon catalyst preparation method, which uses porous silica as a catalyst carrier, and is divided into two steps, wherein the first step comprises: grafting organosilane on the surface of silicon oxide by using a vapor deposition method, increasing the temperature, and introducing an organic matter to perform vapor deposition of carbon at the surface of the silica. With the method of the present invention, the temperature and the energy consumption of the chemical vapor deposition reaction can be greatly reduced so as to effectively reduce the cost of the catalyst. 本发明提供一种负载型炭催化剂的制备方法。以多孔二氧化硅为催化剂载体，制备过程分两步，第一步用气相沉积法在氧化硅表面嫁接有机硅烷，再升高温度通入有机物在二氧化硅表面气相沉积负载炭。该方法可以可大幅度降低化学气相沉积反应温度与能耗，有效降低催化剂的成本。
