摘要
稀土元素作为一种重要的战略资源,被称为“工业维生素”,广泛应用于尖端科技和日常生产生活中,由于其独特的4f电子排布和丰富的电子能级,近年来稀土及其氧化物在电催化领域得到快速发展。本文对稀土氧化物在析氢反应(HER)、析氧反应(OER)、氧还原反应(ORR)、氮还原(NRR)和二氧化碳还原反应(CO_(2)RR)等催化领域的应用进行了整理。总结并讨论了稀土氧化物电催化剂针对不同电催化体系的特点和需求的设计思路,对其在未来的发展和研究重点进行了探讨和展望。
Rare earth elements,as an important strategic resource,are called"industrial vitamins"and widely used in cutting-edge science and technology as well as daily production and life.Due to their unique 4f electron arrangement and abundant electronic energy levels,rare earths and their oxides have been rapidly developed in the field of electrocatalysis in recent years.In this paper,the applications of rare earth oxides in the catalytic fields of hydrogen-extraction reaction(HER),oxygen-extraction reaction(OER),oxygen-reduction reaction(ORR),nitrogen-reduction(NRR),and carbon dioxide-reduction reaction(CO_(2)RR)are organized.The design ideas of rare-earth electrocatalysts for the characteristics and demands of different electrocatalytic systems are summarized and discussed,and their development and research focus in the future are explored and prospected.
