Due to GO’s two dimensional p-conjugation structure andsuperior electric property, it was employed as electron acceptorto be combined with g-C3N4 in the present study to makea composite (GO/g-C3N4). The heterojunction built betweeng-C3N4 and GO is expected to benefit the separation ofphotogenerated electrons and inhibit the electron–hole pairrecombination. The effective charge separation ability canenhance the photocatalytic capability of the GO/g-C3N4 hybridphotocatalyst significantly under visible light irradiation.Rhodamine B (RhB) and 2, 4-dichlorophenol (2,4-DCP) wereused as model substances for photocatalytic degradation reactionsto evaluate the photocatalytic capability of the as preparedGO/g-C3N4 photocatalyst under visible light irradiation(l > 400 nm).
