Controllable Synthesis of Enhanced Visible Light Responded Fe, N, Co Tri-TiO₂@MCM-41 Nanocomposites and Its Photocatalytic Performance.

A novel method for in situ synthesis of Fe, N, Co tri-TiO₂ (DT) loading on MCM-41 composite photocatalyst was proposed. Fe, N, Co tri-TiO₂@MCM-41 (DTM) with adsorption-degradation synergy was prepared by adjusting tetrabutyl titanate (TBOT) concentrations, the alcohol-water ratio in the atmosphere of the reaction chamber. The influence of preparation parameters on the texture structure, catalytic activity, and the synergism of adsorption and degradation of the DTM was discussed, the optimal parameters were determined.
