Abstract

To address the global challenges associated with energy and environmental concerns, the design, development, and application of novel materials have emerged as pivotal drivers. Notably, high-entropy perovskite oxides (HEPOs) amalgamate the merits of both perovskite oxides and high-entropy materials, presenting significant potential in addressing numerous critical issues in energy and environment. This review delves into the recent advancements of HEPOs in these domains. Firstly, it provides an overview of prevalent synthesis techniques for HEPOs, alongside two emerging low-temperature, eco-friendly methods. Subsequently, current strategies to optimize the performance of HEPOs are summarized from three perspectives: compositional engineering, morphological engineering, and structural engineering. The review further underscores their applications in areas such as lithium-ion batteries, supercapacitors, electrocatalysts, and solid oxide fuel cells. Based on this foundation, potential performance optimization strategies and potential application areas of HEPOs are discussed. Finally, it identifies challenges faced by further development of HEPOs in energy and environmental applications and provides an outlook on future developments.

期刊介绍： The word ‘particuology’ was coined to parallel the discipline for the science and technology of particles. Particuology is an interdisciplinary journal that publishes frontier research articles and critical reviews on the discovery, formulation and engineering of particulate materials, processes and systems. It especially welcomes contributions utilising advanced theoretical, modelling and measurement methods to enable the discovery and creation of new particulate materials, and the manufacturing of functional particulate-based products, such as sensors. Papers are handled by Thematic Editors who oversee contributions from specific subject fields. These fields are classified into: Particle Synthesis and Modification; Particle Characterization and Measurement; Granular Systems and Bulk Solids Technology; Fluidization and Particle-Fluid Systems; Aerosols; and Applications of Particle Technology. Key topics concerning the creation and processing of particulates include: -Modelling and simulation of particle formation, collective behaviour of particles and systems for particle production over a broad spectrum of length scales -Mining of experimental data for particle synthesis and surface properties to facilitate the creation of new materials and processes -Particle design and preparation including controlled response and sensing functionalities in formation, delivery systems and biological systems, etc. -Experimental and computational methods for visualization and analysis of particulate system. These topics are broadly relevant to the production of materials, pharmaceuticals and food, and to the conversion of energy resources to fuels and protection of the environment.
