A porous microsphere and a method for preparing the same includes the following steps. A copolymer having a vinylbenzyl chloride unit and a vinylbenzyl alcohol unit is dissolved in an organic solvent, and inorganic particles are dispersed in the organic solvent to form a mixed suspension. An aqueous solution containing a surfactant is provided. The mixed suspension is emulsified in the aqueous solution to form an emulsion. The emulsion is heated to evaporate the organic solvent to obtain inorganic-composite porous microspheres suspended in water. The copolymer in the formed porous microspheres can be further carbonized or removed to produce inorganic-based porous microspheres containing carbon or not containing carbon.

Porous microsphere and method for preparing the same

A copolymer, a method for producing the copolymer, a porous structure formed by the copolymer, a method for producing the porous structure, and a porous carbon sphere formed by carbonizing the porous structure are shown. The copolymer has a chemical structure of formula (1) or (2): wherein the molecular weight of the copolymer structure is 120,000 or less g/mole, m and t are both greater than 0, 8%&#x2264;p&#x2264;80%, y&#x2265;0, z&#x2265;0, and X is selected from &#x2014;Cl, &#x2014;Br and &#x2014;I.
