Method for hydro-thermal synthesis of urchin-like nitrogen-doped hollow carbon microspheres through in-situ self-growth template

The invention discloses a method for hydro-thermal synthesis of urchin-like nitrogen-doped hollow carbon microspheres through an in-situ self-growth template, and belongs to the technical field of material preparation. The preparation method comprises the following specific steps: adding glucose, zinc nitrate, urotropine and trisodium citrate into deionized water according to a certain ratio, uniformly stirring, transferring the turbid liquid into a self-pressure kettle, carrying out hydrothermal treatment to obtain brown powder solid, roasting in an inert atmosphere, and removing a template by using a hydrochloric acid solution to obtain the sea urchin-like nitrogen-doped hollow carbon microsphere material. 一种原位自生长模板水热合成"类海胆状"氮掺杂空心碳微球的方法，属于材料制备技术领域。具体步骤如下：将葡萄糖、硝酸锌、乌洛托品、柠檬酸三钠，以一定比例加入去离子水中，搅拌均匀，然后将上述悬浊液转入自压釜中进行水热处理，得棕色粉末固体，再在惰性气氛中焙烧，盐酸溶液脱除模板，得到"类海胆状"氮掺杂空心碳微球材料。
