1. A method to form a sulfur containing cross-linked porous polymer, comprising:
mixing an aldehyde and a first solvent to form a first mixture;
mixing an organosulfur phenol and an aromatic compound with the first mixture to form a phenol mixture;
heating the phenol mixture in the presence of an acid to form a solid; and
drying the solid to obtain the sulfur containing cross-linked porous polymer;
wherein the sulfur containing cross-linked porous polymer has repeat pyrrole units bonded to one another, and the sulfur containing cross-linked porous polymer has a thiol group which separates non-adjacent pyrrole units;
wherein after the drying the sulfur containing cross-linked porous polymer is in a form of solid particles having a spherical particle structure.
