“…Unquestionably, g-C 3 N 4 /TiO 2 composite is one of the most popular g-C 3 N 4 -based composites and its excellent photocatalytic activity is experimentally verified by a large number of reports. 88,89 Lin et al 90 built a g-C 3 N 4 /TiO 2 (101) composite model in which the equilibrium distance between g-C 3 N 4 and anatase TiO 2 (101) was determined to be 1.94 Å. The interfacial binding energy was 24 meV/Å 2 , suggesting that this composite was assigned to the Van der Waals heterostructure.…”

To improve the photocatalytic performance of pristine photocatalysts, element doping, construction of composites and fabrication of novel nanostructures are recognized as universal modification methods. These methods have been experimentally verified to be effective in manifold photocatalytic application over various photocatalysts. Density functional theory (DFT) calculation is a powerful and fundamental tool to pinpoint the intrinsic mechanism of the enhanced photocatalytic activity. And it holds the degree of precision ranging from atoms, molecules to unit cells. Herein, recent DFT calculation research progress of modified s-triazine-based graphitic carbon nitride (g-C 3 N 4 ) systems as photocatalysts is summarized. To specify, we collected information of doping site, formation energy, geometric, and electronic properties. We also discussed the synergistic effect of work function, Fermi level and band edge position on the built-in electric field, transfer route of photogenerated charge carriers and photocatalytic mechanism (traditional type Ⅱ or direct Z-scheme heterostructure). Moreover, we analyzed the geometric configuration, band structure, and stability of g-C 3 N 4 nanocluster, nanoribbon, and nanotube. Finally, future perspective in the further theoretical revelation of g-C 3 N 4 -based photocatalysts is proposed.

A new carbon quantum dots/porous InVO4 (CQDs/p‐InVO4) microsphere composite was synthesized by a facile reflux method. The relationship of structure and property of CQDs/p‐InVO4 was studied in detail. The results show that the as‐prepared composite samples maintain the porous structure of the p‐InVO4 microspheres, while CQDs are uniformly loaded on the surface of the p‐InVO4 microspheres with an intimate interface. With this unique structure, the as‐obtained samples exhibit enhanced photocatalytic degradation ability towards Rhodamine B (RhB) under visible‐light irradiation. The synergistic effect of more active sites, increased visible‐light absorption, and high separation efficiency of photogenerated electron–hole pairs is believed to be the reason for the enhanced photocatalytic activity.

Light‐Driven Sustainable Hydrogen Production Utilizing TiO₂ Nanostructures: A Review

et al. 2018

View full text Add to dashboard Cite

As a promising alternative clean energy to fossil fuels, H2 has been given increasing attention, and efficient H2 production is urgently required. Photocatalytic H2 generation from water splitting (WS) is deemed to be a promising and green route for H2 production. TiO2 has been widely utilized in WS owing to the stability, low cost, corrosion resistance, and environmental safety properities. Nevertheless, two dominant defects (inferior absorption performance in visible light and recombination of photogenerated e−–h+ pairs) still impede the development of TiO2. This review offers a comprehensive overview of the progress of various routes for TiO2 nanostructures (0D–3D) and diversified modifications for enhanced H2 production. Further, the perspectives and opportunities for TiO2 based materials are promoted. Persistent efforts are needed to equip the TiO2 nanomaterials with original advanced commercialization and functionality.
