Fabrication of TiO2/Co-g-C3N4 heterojunction catalyst and its photocatalytic performance

Abstract A novel heterojunction photocatalyst with well-dispersed TiO2 nanoparticles on Co-Doped g-C3N4 has been successfully fabricated by an in situ generation solvothermal method. The photocatalytic performance of the as-prepared TiO2/Co-g-C3N4 catalyst was evaluated by the degradation of phenol in the presence of Cr6 + under simulated sunlight irradiation. The catalyst exhibited markedly enhanced photocatalytic activity for degradation of phenol but obviously decreased photocatalytic activity for reduction of Cr6 + compared with common TiO2/g-C3N4 catalyst. The mechanism for this photocatalytic performance was proposed.
