Method for preparing high-mesoporosity starch-based mesoporous carbon

The invention belongs to the technical field of chemical materials preparation, and specifically relates to a method for preparing high-mesoporosity starch-based mesoporous carbon. In the method, cheap and easily-acquired soluble starch is used as a raw material, and the high-mesoporosity starch-based mesoporous carbon is prepared by mixing, self-assembling, catalytically dehydrating and carbonizing the raw material. The invention has the advantages that the low-cost high-mesoporosity starch-based mesoporous carbon can be prepared by using the method of synchronously generating a carbon precursor polymer and a template is used, and the method is beneficially applied to the fields such as adsorption, electrochemistry, etc.
