Abstract
The method includes mixing an aldehyde and a first solvent to form a mixture. The method further includes mixing an organosulfur phenol and an aromatic compound to the mixture to form a phenol mixture and heating the phenol mixture in the presence of an acid to form a solid. The solid is dried to obtain the cross-linked porous polymer. The obtained cross-linked porous polymer has repeat pyrrole units bonded to one another, and the cross-linked porous polymer has a thiol group which separates non-adjacent pyrrole units. The cross-linked porous polymer obtained after drying is in a form of solid particles having a spherical particle structure.
