摘要:

电催化技术是可再生能源储存和转换领域中最有吸引力的技术之一, 其中贵金属纳米材料具有优异的电催化活性。贵金属在地球中的储量少且开发成本高, 如何在减少贵金属用量的同时提高催化剂活性和稳定性一直是电催化应用领域的研究焦点。贵金属磷化物作为新型电催化剂因其多功能活性位点、可调的结构和组分以及新颖的物理化学性质等优点, 受到了研究人员的广泛关注。与过渡金属磷化物相比, 贵金属磷化物具有更高的本征活性, 且在酸性条件下具有更好的稳定性。本综述介绍了近年来贵金属磷化物电催化剂的设计合成、结构调控、X射线吸收谱表征及其在电催化应用中的研究进展, 据此讨论当前所面临的机遇和挑战, 并展望原位同步辐射X射线表征技术在未来贵金属磷化物电催化剂研究中的应用前景。

Abstract:

Electrocatalytic technology is one of the most attractive technologies for renewable energy storage and conversion, and nano-scale noble metals exhibit excellent electrocatalytic activity. However, because of the scarcity of precious metal resources and high development costs, reducing the dosage of precious metals while improving activity and durability of catalysts is always the research focus in the field of catalysis applications. Among various candidates, noble metal phosphide-based new electrocatalysts have received widespread attention due to their multifunctional active sites, adjustable structure and composition, and unique physical and chemical properties. Compared with transition metal phosphide, noble metal phosphides have higher intrinsic activity, and exhibit better stability under acid condition. In this review, the research progress of noble metal phosphides was mainly summarized including design synthesis, structural engineer, X-ray absorption spectroscopic characterization, and electrocatalytic applications. Eventually, the current challenges and opportunities for the development of noble metal phosphide-based electrocatalysts were discussed, along with the future prospection of in situ synchrotron radiation X-ray characterizations that might be applied in this field.

Key words: noble metal phosphide, electrocatalysis, synchrotron radiation, X-ray absorption spectroscopy, review
