摘要

Abstract

Porous g-C

samples were obtained by simply calcining bulk g-C

in static air in a muffle oven. The photocatalytic performance of these samples was evaluated through the removal of aqueous organic dyes (methylene blue and methyl orange) and tetracycline hydrochloride under visible-light irradiation (λ 420 nm). Compared to bulk g-C

porous g-C

exhibited much better capability for removing these contaminants

especially under visible-light irradiation

due to the enlarged specific surface area and more efficient separation of photogenerated charge carries. In particular

porous g-C

obtained by calcining bulk g-C

in air at 525℃ showed the highest visible-light-driven catalytic activity among these samples. Superoxide radical anions (·O

) were found to be the primary active species responsible for photodegradation.
