“…Graphene with a two-dimensional structure has a large number of two-dimensional conjugated structures, so people combine graphene with TiO 2 to enhance the photocatalytic performance of TiO 2 , which has been extensively studied in this area. Heltina [117], Wang [118], and others prepared TiO 2 with different graphene (GO) composite ratios compared to the pure TiO 2 and the composite TiO 2 /GO catalysts. The smaller grain size and higher adsorbed oxygen/lattice oxygen ratio exhibited superior photocatalytic performance.…”

Titanium dioxide (TiO2) photocatalysts, characterized by exceptional photocatalytic activity, high photoelectric conversion efficiency, and economic viability, have found widespread application in recent years for azo dye degradation. However, inherent constraints, such as the material’s limited visible light absorption stemming from its bandgap and the swift recombination of charge carriers, have impeded its broader application potential. Encouragingly, these barriers can be mitigated through the modification of TiO2. In this review, the common synthesis methods of TiO2 are reviewed, and the research progress of TiO2 modification technology at home and abroad is discussed in detail, including precious metal deposition, transition metal doping, rare earth metal doping, composite semiconductors, and composite polymers. These modification techniques effectively enhance the absorption capacity of TiO2 in the visible region and reduce the recombination rate of carriers and electrons, thus significantly improving its photocatalytic performance. Finally, this paper looks forward to the future development direction of TiO2 photocatalytic materials, including the exploration of new modified materials, in-depth mechanism research, and performance optimization in practical applications, to provide useful references for further research and application of TiO2 photocatalytic materials.

Nanostructured‐based photocatalysts have always exhibited the potential to solve various environmental issues resulting from global urbanization and industrialization. The creation of nanostructured materials has given humans access to various techniques for treating the numerous inorganic and organic contaminants found in wastewater from multiple sources. Due to their exceptional photocatalytic activity, semiconductor materials, among various other materials have different environmental uses. Studying nanocomposites of titanium dioxide (TiO2) and carbon‐based material, particularly graphene‐based material, is one of the burgeoning research areas of visible‐light‐driven photocatalysts. It has been demonstrated that the combination of graphene‐based material with titanium dioxide is more successful than titanium dioxide alone in photocatalysis. TiO2/graphene‐based nanocomposites stand out due to their superior physical and chemical characteristics, such as their moderate band gap, high specific surface area, nontoxic, low cost, high corrosion resistance, high photoactivity, stability, and ease of handling in various configurations. Designing high‐performance TiO2/graphene‐based photocatalysts has drawn more and more attention. This study has evaluated TiO2/graphene‐based nanocomposites for photocatalytic environmental applications from 2022 to 2024. These nanocomposites' diverse preparation methods have been discussed. The recent discoveries in TiO2/graphene‐based nanocomposite composites and their uses in photocatalysis, such as wastewater treatment to remove contaminants and photoconversion of CO2 into renewable fuels are also briefly discussed in this review.
