纳米TiO2由于其优异的物化性能,在众多领域具有广阔的应用前景。但其较宽能隙、较快的光生载流子复合速度等缺点,严重制约了在光电、光催化及其他领域的实际应用。近年来,对氧化钛纳米材料进行表面氢化的改性手段,取得了不少研究成果。主要综述了目前纳米氧化钛表面氢化的方法,总结了相关机理,并介绍了主要的应用进展,展望了纳米材料表面氢化的研究方向。
Due to its excellent physical and chemical properties, nano-TiO2 has broad application prospects in many fields. However, its wide gap, fast photogenerated carrier recombination speed and other shortcomings seriously hampered the practical application in optoelectronics, photocatalysis and other fields. In recent years, titanium dioxide nanomaterials surface hydrogenation modification means, and made a lot of research results. The methods of hydrogenation on the surface of nano-titanium oxide are reviewed. The relevant mechanisms are summarized. The main application progress is also described. The research directions of the surface hydrogenation of nano-materials are also prospected.
