Abstract

High-entropy nanoparticles (HE-NPs) have recently gained considerable attention owing to their potential to yield several materials with unique characteristics due to the homogeneous mixing of five or more elements. The complexity of HE-NPs leads to electronic hybridization, lattice distortion, and sluggish diffusion effects, all of which contribute to their performance and stability. The formation of HE-NPs is thermodynamically limited, particularly by enthalpic factors. To overcome these limitations and design intricate nanostructures, wet chemistry can be employed as a relatively straightforward synthesis method. This review provides an overview of HE-NPs, including their definition, thermodynamic principles, and wet-chemical synthesis methods. It further explores the diverse range of applications of HE-NPs and examines how specific nanoparticle morphologies and compositions can be tailored efficiently using various synthesis strategies. Additionally, this review discusses case studies presenting optimized HE-NPs for individual applications, demonstrating their high performance. By identifying the key factors that contribute to their superior performance, this review offers valuable insights into future research directions for HE-NPs.

合成高熵纳米颗粒的湿化学方法:合成策略与各种应用综述
高熵纳米粒子(HE-NPs)由于具有五种或更多元素均匀混合的特性,可产生多种具有独特特性的材料,因此最近受到了广泛关注。HE-NPs 的复杂性导致电子杂化、晶格畸变和扩散效应迟缓,所有这些都有助于提高其性能和稳定性。HE-NPs 的形成受到热力学的限制,尤其是焓因素的限制。为了克服这些限制并设计出复杂的纳米结构,湿化学是一种相对简单的合成方法。本综述概述了 HE-NPs 的定义、热力学原理和湿化学合成方法。它进一步探讨了 HE-NPs 的各种应用,并研究了如何利用各种合成策略有效地定制特定的纳米粒子形态和成分。此外,本综述还讨论了一些案例研究,介绍了针对个别应用进行优化的 HE-NPs,展示了它们的高性能。本综述通过确定促成其卓越性能的关键因素,为 HE-NPs 的未来研究方向提供了宝贵的见解。

期刊介绍: The Korean Journal of Chemical Engineering provides a global forum for the dissemination of research in chemical engineering. The Journal publishes significant research results obtained in the Asia-Pacific region, and simultaneously introduces recent technical progress made in other areas of the world to this region. Submitted research papers must be of potential industrial significance and specifically concerned with chemical engineering. The editors will give preference to papers having a clearly stated practical scope and applicability in the areas of chemical engineering, and to those where new theoretical concepts are supported by new experimental details. The Journal also regularly publishes featured reviews on emerging and industrially important subjects of chemical engineering as well as selected papers presented at international conferences on the subjects.
