- 摘要:
- 高熵氧化物是由多种金属或非金属氧化物以等或近等比例固溶形成的单一结构氧化物，在电化学储能领 域有着广泛的应用前景。本论文介绍了高熵氧化物现有优点(鸡尾酒效应、高熵效应、晶格畸变效应等)和合成方法，其主 要包括高温固相反应法、热解法、共沉淀法、溶液燃烧合成法、水热合成法，以及基于其优异性能在催化制氢、超级电容 器、锂电池等电化学储能领域的应用，综述了高熵氧化物在电化学储能领域的研究进展。A high-entropy oxide is a single structural oxide formed from a solid solution of a variety of metal or nonmetal oxides in equal or nearly equal proportions and has wide application prospects in the field of energy. This paper mainly introduces the advantages of high-entropy oxides (cocktail effects, high-entropy effects, lattice distortion effects, etc.) and synthesis methods, which mainly include the high-temperature solid-phase reaction method, pyrolysis method, coprecipitation method, solution combustion synthesis method, and hydrothermal synthesis method, and on the basis of their excellent performance in catalytic hydrogen production, supercapacitors, lithium batteries and other electrochemical energy storage applications. The research progress on high-entropy oxides in the field of electrochemical energy storage is reviewed.
