高熵材料是一类新生的材料,其利用高构型熵来稳定单晶晶格中的多个元素,并产生用于能量存储、催化和热电能量转换的独特物理性质。最初,这些材料的合成是通过需要高温和长合成时间尺度的方法进行的。然而,在晶格内的原子水平上成功地均匀混合元素仍然具有挑战性,特别是对于纳米材料的合成。使用原子向上的合成方法来逐个原子地构建晶格,而不是自上而下地改变现存的晶格,可以导致更快,更低温度和更可持续的方法来获得高熵材料。在这个视角中,我们讨论了一些最先进的高熵材料的原子合成方法,并将它们与更传统的方法进行了对比。在这个观点中,刘易斯和同事讨论了一些最先进的原子合成方法,以高熵无机材料,比较和对比他们与更传统的方法。
High-entropy materials are a nascent class of materials that exploit a high configurational entropy to stabilize multiple elements in a single crystal lattice and to yield unique physical properties for applications in energy storage, catalysis, and thermoelectric energy conversion. Initially, the synthesis of these materials was conducted by approaches requiring high temperatures and long synthetic time scales. However, successful homogeneous mixing of elements at the atomic level within the lattice remains challenging, especially for the synthesis of nanomaterials. The use of atom-up synthetic approaches to build crystal lattices atom by atom, rather than the top-down alteration of extant crystalline lattices, could lead to faster, lower-temperature, and more sustainable approaches to obtaining high entropy materials. In this Perspective, we discuss some of these state-of-the-art atom-up synthetic approaches to high entropy materials and contrast them with more traditional approaches. In this Perspective Lewis and co-workers discuss some of the state-of-the-art atom-up synthetic approaches toward high entropy inorganic materials, comparing and contrasting them with more traditional methods.
