Method for preparing nano mesoporous carbon microspheres by adopting soft template

The invention discloses a method for preparing nano mesoporous carbon microspheres by adopting a soft template. The method particularly comprises the steps that structure-directing agents and a carbon source are added into and mixed with an alkaline solution with pH equaling to 12 to assemble a complex, heat aging is conducted on the complex, and carbonization is conducted on the aging product to obtain the nano mesoporous carbon microspheres. Compared with the prior art, by means of the method for preparing the nano mesoporous carbon microspheres by adopting the soft template, the nano mesoporous carbon microspheres with high specific areas and controllable pore passage structures can be prepared at a lower temperature ranging from 130 DEG C to 150 DEG C, dosages of the structure-directing agents and the carbon source can be adjusted according to actual requirements, and therefore adjustment and control of the pore passage structures can be conducted. Meanwhile, the method for preparing the nano mesoporous carbon microspheres by adopting the soft template has the advantages of being short in production cycle, simple in technology and low in cost.
