Electrocatalytic water splitting, as a sustainable, pollution-free and convenient method of hydrogen production, has attracted the attention of researchers. However, due to the high reaction barrier and slow four-electron transfer process, it is necessary to develop and design efficient electrocatalysts to promote electron transfer and improve reaction kinetics. Tungsten oxide-based nanomaterials have received extensive attention due to their great potential in energy-related and environmental catalysis. To maximize the catalytic efficiency of catalysts in practical applications, it is essential to further understand the structure-property relationship of tungsten oxide-based nanomaterials by controlling the surface/interface structure. In this review, recent methods to enhance the catalytic activities of tungsten oxide-based nanomaterials are reviewed, which are classified into four strategies: morphology regulation, phase control, defect engineering, and heterostructure construction. The structure-property relationship of tungsten oxide-based nanomaterials affected by various strategies is discussed with examples. Finally, the development prospects and challenges in tungsten oxide-based nanomaterials are discussed in the conclusion. We believe that this review provides guidance for researchers to develop more promising electrocatalysts for water splitting.
电催化水分解作为一种可持续、无污染且便捷的制氢方法，已引起研究人员的关注。然而，由于高反应势垒和缓慢的四电子转移过程，有必要开发和设计高效的电催化剂以促进电子转移并改善反应动力学。基于氧化钨的纳米材料因其在能源相关和环境催化方面的巨大潜力而受到广泛关注。为了在实际应用中最大化催化剂的催化效率，通过控制表面/界面结构进一步理解基于氧化钨的纳米材料的结构-性能关系至关重要。在这篇综述中，回顾了近期提高基于氧化钨的纳米材料催化活性的方法，这些方法分为四种策略：形貌调控、相控制、缺陷工程和异质结构构建。通过实例讨论了各种策略对基于氧化钨的纳米材料结构-性能关系的影响。最后，在结论部分讨论了基于氧化钨的纳米材料的发展前景和挑战。我们相信这篇综述为研究人员开发更有前景的用于水分解的电催化剂提供了指导。
