Abstract
Two-dimensional (2D) graphitic carbon nitride (g-C 3 N 4 ) has invoked significant interest for photocatalytic applications for its excellent features such as high surface area, visible light absorption, and easy transportation of photogenerated charge carriers, but the most reported g-C 3 N 4 show relatively low photoactivity due to inferior conductivity and rapid recombination of carriers. These can be overcome by inducing porosity in g-C 3 N 4 , followed by exfoliation and combining with other materials. Herein, we synthesize nanocavity-assisted oxygen-deficient Ti 3+ self-doped blue TiO 2 (B) nanorods (BT) and integrate them on exfoliated porous g-C 3 N 4 (PCN). The synthesized materials are tested for photocatalytic conversion of CO 2 into solar fuels (H 2 , CO, and CH 4 ). The fabricated BT/PCN heterostructures exhibit higher photocatalytic CO 2 conversion activity and 92% CO-evolving selectivity than BT and PCN. The enhancement in activity of BT/PCN can be attributed to the efficient separation and transportation of charge carriers, facilitated by the unique properties of BT, PCN, and their synergistic interactions. We believe that these results can contribute to the improvement of cost-effectiveness, feasibility, and overall performance for real photocatalytic systems. • Synthesis of nanocavity-assisted Ti 3+ Self-Doped Blue TiO 2 (B) (BT) by simple methods. • Conversion of bulk g-C 3 N 4 into a few layered porous g-C 3 N 4 (PCN) by exfoliation process. • The integration of BT on PCN accelerates charge separation and migration. • High absorption capacity and well-aligned band potentials of composite improve the activity. • The optimized BT/PCN shows a high rate of CO 2 conversion into solar fuels production.
