One-step synthesis of MoS2/g-C3N4 nanocomposites with highly enhanced photocatalytic activity

A facile one-step synthesis of MoS2/g-C3N4 nanocomposites by in situ thermal polycondensation was reported. The MoS2/g-C3N4 exhibited looser, thinner and bimodal mesoporous features. The MoS2 species were uniform and compact on the surface of g-C3N4 to obtain a robust heterojunction. Benefiting from the structure merits, the MoS2/g-C3N4 exhibited superior visible-light induced activity and good cycle stability for photodegradation of rhodamine B. The enhancement of visible-light absorption and the suppression of recombination of photogenerated carriers were responsible for highly enhanced activity.
