The invention discloses a method for preparing a transition metal oxide/carbon composite material by using solar energy. The method comprises the steps of adopting different transition metal base bodies such as sheet metal, mesh metal or foamed metal to act as a carrier and a metal source, using a biomass water solution such as starch, glucose or sucrose to act as a carbon source, then placing the metal base body coated with a biomass film at the focus of a focusing sunlight beam, controlling the temperature and time, and preparing a transition metal oxide/carbon composite material at the surface of the metal base body. The method disclosed by the invention does not need expensive instruments, low in raw material cost and easy to realize different synthesis scales. 本发明公开了种利用太阳能制备过渡金属氧化物/碳复合材料的方法。采用不同过渡金属基体（片、网或泡沫）作为载体和金属源，利用淀粉、葡萄糖或蔗糖等等生物质水溶液作为碳源，然后将涂覆生物质薄膜的金属基体置于聚焦太阳光束的焦点处，控制温度和时间，在金属基体表面制备出过渡金属氧化物/碳复合材料。该制备方法简单方便，无需大型贵重仪器，原材料成本低，容易实现不同的合成规模。
