摘要
Advances in energy conversion and storage technologies,such as water electrolyzers,rechargeable metal-air batteries,and fuel cells,have enabled a renewable and sustainable future.The efficiency and effectiveness of these technologies largely relies on the physicochemical properties of the functional materials used,specifically electrocatalysts.Pulsed laser deposition(PLD)is a powerful technique for the synthesis of thin film materials,offering a unique platform for understanding electrochemical reaction mechanisms and searching for low-cost and high-performance electrocatalysts.In this mini-review,we present the latest studies in which thin film materials(mainly focused on perovskite oxide thin films)via PLD have been actively utilized in the field of electrocatalysis.The fundamentals and advantages of PLD in the synthesis of thin films are discussed first.Then,emerging types of thin films associated with electrochemical applications are presented.Special emphasis is placed on material design methods to reveal the reaction mechanisms and establish the structure–performance relationships by understanding structural variations in precatalysts and surface reconstruction under reaction conditions.Finally,we discuss remaining challenges and future perspectives.
