In this study, polymer spheres (PSs) were prepared by an emulsion polymerization of resorcinol, pyrocatechol, or 3-hydroxypyridine with formaldehyde under basic conditions. Carbon spheres (CSs) were obtained by carbonization of PSs at 900°C, and some of them were activated with KOH and oxygen adsorption-desorption cycles. Resorcinol and pyrocatechol differ in their reactivity during the polycondensation...
