Abstract:
With the increasing popularity of photocatalytic technology and the highly growing issues of energy scarcity and environmental pollution, there is an increasing interest in extremely efficient photocatalytic systems. The widespread immense attention and applicability of Nb2O5 photocatalysts can be attributed to their multiple benefits, including strong redox potentials, non-toxicity, earth abundance, corrosion resistance, and efficient thermal and chemical stability. However, the large-scale application of Nb2O5 is currently impeded by the barriers of rapid recombination loss of photo-activated electron/hole pairs and the inadequacy of visible light absorption. To overcome these constraints, plentiful design strategies have been directed at modulating the morphology, electronic band structure, and optical properties of Nb2O5. The current review offers an extensive analysis of Nb2O5-based photocatalysts, with a particular emphasis on crystallography, synthetic methods, design strategies, and photocatalytic mechanisms. Finally, an outline of future research directions and challenges in developing Nb2O5-based materials with excellent photocatalytic performance is presented.
摘要:
随着光催化技术的日益普及和能源紧缺和环境污染等问题日益严重,对极其有效的光催化体系的兴趣日益增加。Nb2O5光催化剂的广泛关注和适用性可以归因于它们的多重优点,包括强氧化还原电位,无毒性,地球丰度,耐腐蚀性,和有效的热和化学稳定性。然而,目前,由于光活化电子/空穴对的快速复合损失和可见光吸收不足,阻碍了Nb2O5的大规模应用。为了克服这些限制,丰富的设计策略已经针对调节形态,电子能带结构,Nb2O5的光学性质。当前的评论提供了基于Nb2O5的光催化剂的广泛分析,特别强调晶体学,合成方法,设计策略,和光催化机理。最后,概述了未来开发具有优异光催化性能的Nb2O5基材料的研究方向和挑战。
