Hybridization of brookite TiO₂ with g-C₃N₄: a visible-light-driven photocatalyst for As³⁺ oxidation, MO degradation and water splitting for hydrogen evolution

Abstract

A visible-light-driven photocatalyst of brookite TiO2 coupled with g-C3N4 exhibited high efficiency for As3+ oxidation, MO degradation, and hydrogen evolution.

Defective graphitic carbon nitride synthesized by controllable co-polymerization with enhanced visible light photocatalytic hydrogen evolution

“…1 The central task of the process is to develop highly efficient and low cost photocatalysts, which has been a continuing worldwide effort since the pioneer work in 1972 by Fujishima and Honda. 2 Substantial photocatalysts such as metal oxides, sulfides, nitrides and doped perovskites [3][4][5][6][7][8] have been used to explore the photocatalytic hydrogen evolution. However, industrial applications are unsatisfied in consideration of the efficiency, economy, stability and toxicity issues.…”

In situ growth of TiO2 nanocrystals on g-C3N4 for enhanced photocatalytic performance

“…Park et al developed novel visible light active graphitic carbon nitride TiO 2 composite through a thermal transformation methodology. In view of the previous studies, there are mainly three strategies for the preparation of the TiO 2 /g-C 3 N 4 composite: (1) mixing the presynthesized TiO 2 and g-C 3 N 4 by means of heating, grinding or ball milling [30][31][32][33] ;…”
