In situ synthesis of g-C3N4/TiO2 heterostructures with enhanced photocatalytic hydrogen evolution under visible light
journal contribution
posted on 2022-10-26, 04:32 authored by H Zhang, F Liu, H Wu, X Cao, J Sun, Weiwei LeiWeiwei LeiGraphitic carbon nitride (g-C3N4) nanosheets/titanium dioxide (TiO2) nanoparticles heterostructures have been in situ synthesized via a modified sol-gel method combined with a calcination process. The prepared g-C3N4/TiO2 heterostructured composites exhibited excellent photocatalytic hydrogen generation from water splitting under visible light irradiation. It was found that the TiO2 nanoparticles are well-dispersed on the g-C3N4 nanosheets. The as-obtained g-C3N4 coupled with TiO2 not only increased the surface area of g-C3N4, but also promoted the separation of photo-generated charge carriers. The developed composite exhibits an excellent hydrogen evolution rate of 40 μmol h-1, which is about 2.7 times higher than that of pure g-C3N4 nanosheets.
