研究目的
To summarize the preparation methods of 2D material/TiO2 hybrid and explore the role of 2D materials in enhancing photocatalysis activities.
研究成果
The coupling between TiO2 and 2D material has proven to be an efficient approach to enhanced photocatalytic activity. Different methods vary the structures and surface contact of the hybrid and thus can modify the carrier separation process. The synergistic effects show that 2D material plays a vital role in photocatalysis when composited with TiO2.
研究不足
The review highlights the limitations of traditional TiO2 photocatalysts, such as ineffective use of sunlight and rapid carrier recombination rate. It also discusses the challenges in controlling the modification between TiO2 and 2D materials to ensure strong interactions and uniform dispersion.
