3.2.3 Physical-chemical activation method <br>Physical-chemical activation method refers to a combination of chemical and physical methods to prepare an activation method. This is a novel activation method. It has mutual assistance in terms of cost, process complexity and pore size distribution control. It is usually used to study pore structure regulation. Before physical activation, the precursor needs to be chemically modified. The physical-chemical activation method not only effectively controls the pore size and specific surface area of ​​activated carbon, but also controls the type of pores. Porous carbon materials containing only mesopores or only micropores can be prepared according to different requirements.

3.2.3 Physical-chemical activation<br> Physical-chemical activation is the combination of chemical and physical methods to prepare activation. This is a novel method of activation. It has mutual support in terms of cost, process complexity and aperture distribution regulation. It is commonly used to study hole structure regulation. Prior to physical activation, chemical modification of the precursor body is required. The physical-chemical activation method not only effectively controls the aperture and ratio of activated carbon, but also controls the type of pore. A porous carbon material containing only medium holes or only micropores can be prepared according to different requirements.

3.2.3 physical chemical activation method<br>Physical chemical activation method is a combination of chemical and physical methods to prepare activation method. This is a novel activation method. It can help each other in cost, process complexity and pore size distribution control. It is usually used to study pore structure regulation. Before physical activation, chemical modification of precursors is needed. The physical-chemical activation method not only effectively controls the pore size and specific surface product of activated carbon, but also controls the type of pore. Porous carbon materials containing only mesopores or micropores can be prepared according to different requirements.<br>
