Our work provides an approach to overcome the defect of pure g-C 3N 4, which accesses to composite with the second component matched well.įujishima, A. The superior performance can be related to an enhanced electron lifetime, the promoted charge transfer and the increased electronic separation property of g-C 3N 4. According to surface photo-voltage spectra, electrochemical CO 2 reduction, photoluminescence, etc. The developed g-C 3N 4/MgTi 2O 5 nanocomposites with a 5 wt.% MgTi 2O 5 exhibits the highest H 2 and CO yield under visible light and excellent stability compare to the other MgTi 2O 5 contents in composites. The photocatalytic performance of the nanocomposites was measured by hydrogen production and CO 2 reduction under visible light. Additionally, compositing metal oxides of MgTi 2O 5 with g-C 3N 4 has proven to be a proper strategy to accelerate surface catalytic reactions in g-C 3N 4, and the photoinduced carriers were modulated to maintain thermodynamic equilibrium, which convincingly promotes the photocatalytic activity. Different from common approaches, here, we propose an innovative method to construct g-C 3N 4/MgTi 2O 5 nanocomposites featuring “0 + 1 > 1” magnification effect to improve g-C 3N 4 photocatalytic performance under visible light irradiation. As for this, MgTi 2O 5 with high chemical stability, wide band gap and negative conduction band was used as a suitable platform for coupling with g-C 3N 4 to enhance charge separation and promoted the photoactivity. However, the bulk g-C 3N 4 photocatalyst has the low separation efficiency of photogenerated carriers and unsatisfied surface catalytic performance, which leads to poor photocatalytic performance. Graphitic carbon nitride (g-C 3N 4) has become an attractive visible-light-responsive photocatalyst because of its semiconductor polymer compositions and easy-modulated band structure.
