摘要:

纳米材料的“相”(即原子排列方式)是决定其物理化学性质及功能的核心因素之一。近年来,纳米材料相工程(phase engineering of nanomaterials, PEN)已经成为材料科学领域新兴的研究方向。通过精确调控原子排列方式,PEN不仅能够突破材料常规的热力学稳定相的限制,还能赋予新的非常规相材料独特的物理化学性质和功能,为开发新型功能纳米材料提供了全新策略。本文系统综述了利用PEN策略来制备新的非常规相贵金属和过渡金属二硫族化合物(TMDs),总结了直接合成、诱导相变等关键制备方法,阐明了其相依赖的性质和催化性能,强调了相对其功能和应用的显著影响。同时,本文深入分析了当前研究中存在的挑战,提出了未来发展方向,包括合成机制的研究、非常规相材料的稳定性提升以及人工智能辅助设计等,以期为纳米材料相工程的基础研究与实际应用提供理论指导和技术参考。

Abstract:

Phase, which refers to the long-range ordered atomic arrangement, is one of the key parameters to determine the physicochemical properties and functions of nanomaterials. Recently, phase engineering of nanomaterials (PEN) has emerged as a promising research direction in materials science, since precise control over atomic arrangements enables the synthesis of nanomaterials with unconventional phases that are different from their thermodynamically stable counterparts, resulting in unique physicochemical properties. Therefore, PEN provides a new strategy for developing novel functional nanomaterials to enhance their performance in various applications. This review focuses on PEN strategies for preparing novel noble metals and transition metal dichalcogenides (TMDs) with unconventional phases. It provides a comprehensive summary of crucial synthetic methods, such as direct synthesis and phase transformation, demonstrates their phase-dependent properties and catalytic performance, and highlights the significant impact of phase on the functions and applications of nanomaterials. Finally, we discuss the challenges and future directions for PEN, including in-depth studies on synthetic mechanisms, effective strategies to improve the stability of unconventional-phase nanomaterials, and innovative AI-aided structural design. These efforts aim to provide theoretical and technical guidance on both fundamental research and practical applications in the field of PEN.
