摘要
Ruddlesden-Popper(RP)型钙钛矿氧化物具有独特的理化性质,被认为是一种极具潜力的固体氧化物燃料电池(SOFCs)阳极材料,但是多数现有RP型钙钛矿存在不耐还原、催化氧化活性或稳定性不足等问题.在简要介绍RP型氧化物的基础上,总结出其结构可调和性质特异的内在机理,基于材料微观结构的维度、离子取代位点、制备工艺特性等系统地介绍了近年其作为SOFCs阳极的研究进展,并对制备RP型材料使用的相转变法及提升催化活性的原位析出进行了梳理与探讨,重点分析了 RP型钙钛矿氧化物用于SOFCs阳极的设计理念和目前仍然存在的问题.最后指出利用异价离子取代、理论实践结合、充分利用氧非计量比是开发耐还原且具有高催化活性和稳定性的新型RP阳极的重要策略.
Abstract
Ruddlesden-Popper(RP)perovskite oxide has a set of distinct physicochemical characteristics that make it a highly promising anode for solid oxide fuel cells(SOFCs).However,it is hard to use most RP perovs-kites directly in anodes because they lack reduction resistance,catalytic activity or stability.This review sum-marizes the internal mechanism of structure adjustability and properties richness of RP oxide based on the brief introduction of its characteristics,and then systematically introduces recent advances in RP oxide as an anode for SOFCs based on the dimension of microstructure,ion substitution sites and preparation process characteris-tics.Then reviews and discusses the ingenious phase transformation method used in preparing materials and in situ precipitation to improve catalytic activity,and extensively analyzes the design concept of the RP materials and the existing problems.Finally,this review indicates that the substitution with heterovalent ion,the combi-nation of theory and practice,the full use of oxygen non-stoichiometric ratio and hydroxylation ability of RP ox-ide are important strategies to develop new RP anodes with higher reduction resistance,catalytic activity and stability.
