Photodegradation performance of g C3N4 fabricated by directly heating melamine.
The g C(3)N(4) photocatalyst was synthesized by directly heating the low cost melamine. The methyl orange dye (MO) was selected as a photodegrading goal to evaluate the photocatalytic activity of as prepared g C(3)N(4) The comparison experiments indicate that the photocatalytic activity of g C(3)N(4) can be largely improved by the Ag loading. The strong acid radical ion (SO(4)(2 or NO(3) can promote the degrading rate of MO for g C(3)N(4) photocatalysis system. The MO degradation over the g C(3)N(4) is mainly attributed to the photoreduction process induced by the photogenerated electrons. Our results clearly indicate that the metal free g C(3)N(4) has good performance in photodegradation of organic pollutant.
