“…Furthermore, GD with diacetylene linkage can be chemically bonded with TiO 2 [82][83][84][85]. Therefore, the TiO 2 -graphdiyne composites can greatly improve the photocatalytic activity, and thus their application in photocatalysis has been explored recently [83,84,86].…”

“…Despite of film, GD with different morphologies such as nanotube arrays, nanowires, nanowalls and nanosheets have been also prepared for diverse applications [87,88]. Ex-situ hydrothermal method is commonly used in preparation of GD/TiO 2 composites [83,84,86]. In general, the GD and TiO 2 are prepared separately.…”

“…The calculated results were in accordance with theoretical prediction that TiO 2 (001)-GD composites showed the highest photocatalysis performance among 2D carbon-based TiO 2 composites, confirming that GD could become a promising competitor in the field of photocatalysis. After that, Dong et al prepared GD-hybridized nitrogen-doped TiO 2 nanosheets with exposed (001) facets (GD-NTNS) [86]. The doped N and incorporated GD efficiently narrowed the bandgap compared with pure TiO 2 and widened response range towards light from UV light to 420 nm visible light.…”

“…The activity of the GD-NTNS photocatalyst presented the most superior performance compared with bare TiO 2 nanosheets (TNS) and nitrogen-doped TiO 2 nanosheets (NTNS) and GR-NTNS. Ex-situ hydrothermal method is commonly used in preparation of GD/TiO2 composites [83,84,86]. In general, the GD and TiO2 are prepared separately.…”

Energy shortage and environmental pollution problems boost in recent years. Photocatalytic technology is one of the most effective ways to produce clean energy—hydrogen and degrade pollutants under moderate conditions and thus attracts considerable attentions. TiO2 is considered one of the best photocatalysts because of its well-behaved photo-corrosion resistance and catalytic activity. However, the traditional TiO2 photocatalyst suffers from limitations of ineffective use of sunlight and rapid carrier recombination rate, which severely suppress its applications in photocatalysis. Surface modification and hybridization of TiO2 has been developed as an effective method to improve its photocatalysis activity. Due to superior physical and chemical properties such as high surface area, suitable bandgap, structural stability and high charge mobility, two-dimensional (2D) material is an ideal modifier composited with TiO2 to achieve enhanced photocatalysis process. In this review, we summarized the preparation methods of 2D material/TiO2 hybrid and drilled down into the role of 2D materials in photocatalysis activities.

Graphdiyne (GDY) is regarded as an exceptional candidate to meet the growing demand in many fields due to its rich chemical bonds, highly π‐conjugated structure, uniformly distributed pores, large surface area, and high inhomogeneity of charge distribution. The extensive research efforts bring about a rapid expansion of GDY with a variety of functionalities, which significantly enhance performance including photocatalysis, energy, biomedicine, etc. In this review, the synthetic strategies (in situ and ex situ approaches) that are designed to rationally functionalize GDY, including optimizing their nanostructures by surface/interface engineering with dopants or functional groups (heteroatoms/small molecules/macromolecules), and building up hierarchical GDY‐based heterostructures are highlighted. Theoretical calculations on the structural evolution and electronic characteristics after the functionalization of GDY are briefly discussed. With elaborate functionalization and rational structure engineering, functional GDY applied in a variety of emerging applications (e.g., hydrogen evolution reaction, CO2 reduction reaction, nitrogen reduction reaction, energy storage and conversion, nanophotonics, sensors, biomedical applications, etc.) are comprehensively discussed. Finally, challenges and prospects concerning the future development of GDY‐based nanoarchitectures are also presented.
