Because of the combined merits of rich physicochemical properties, abundance, low toxicity, , hematite (α-FeO), one of the most chemically stable compounds based on the transition metal element iron, is endowed with multifunctionalities and has steadily been a research hotspot for decades. Very recently, advanced α-FeO materials have also been developed for applications in some cutting-edge fields. To reflect this trend, the latest progress in developing α-FeO materials for newly emerging applications is reviewed with a particular focus on the relationship between composition/nanostructure-induced electronic structure modulation and practical performance. Moreover, perspectives on the critical challenges as well as opportunities for future development of diverse functionalities are also discussed. We believe that this timely review will not only stimulate further increasing interest in α-FeO materials but also provide a profound understanding and insight into the rational design of other materials based on transition metal elements for various applications.
由于具有丰富的物理化学性质、储量丰富、毒性低等综合优点，赤铁矿（α-Fe₂O₃）作为基于过渡金属元素铁的化学性质最稳定的化合物之一，具有多种功能，并且几十年来一直是研究热点。最近，先进的α-Fe₂O₃材料也已被开发用于一些前沿领域。为反映这一趋势，本文综述了开发用于新兴应用的α-Fe₂O₃材料的最新进展，特别关注成分/纳米结构诱导的电子结构调制与实际性能之间的关系。此外，还讨论了各种功能面临的关键挑战以及未来发展机遇。我们相信，这一及时的综述不仅将激发对α-Fe₂O₃材料的进一步兴趣，还将为基于过渡金属元素的其他材料在各种应用中的合理设计提供深刻的理解和见解。
