Amorphous alloys structurally deviate from crystalline materials in that they possess unique short-range ordered and long-range disordered atomic arrangement. They are important catalytic materials due to their unique chemical and structural properties including broadly adjustable composition, structural homogeneity, and high concentration of coordinatively unsaturated sites. As chemically reduced metal-metalloid amorphous alloys exhibit excellent catalytic performance in applications such as efficient chemical production, energy conversion, and environmental remediation, there is an intense surge in interest in using them as catalytic materials. This critical review summarizes the progress in the study of the metal-metalloid amorphous alloy catalysts, mainly in recent decades, with special focus on their synthetic strategies and catalytic applications in petrochemical, fine chemical, energy, and environmental relevant reactions. The review is intended to be a valuable resource to researchers interested in these exciting catalytic materials. We concluded the review with some perspectives on the challenges and opportunities about the future developments of metal-metalloid amorphous alloy catalysts.
非晶态合金在结构上与晶态材料不同，它们具有独特的短程有序和长程无序原子排列。由于其独特的化学和结构性质，包括广泛可调的组成、结构均一性和高浓度的配位不饱和位点，它们是重要的催化材料。作为化学还原的金属-类金属非晶态合金在高效化学生产、能源转化和环境修复等应用中表现出优异的催化性能，因此人们对它们作为催化材料的兴趣日益浓厚。这篇重要的综述总结了金属-类金属非晶态合金催化剂研究的进展，主要集中在最近几十年，特别关注了它们在石油化工、精细化工、能源和环境相关反应中的合成策略和催化应用。本文旨在为对这些令人兴奋的催化材料感兴趣的研究人员提供有价值的资源。我们在综述的最后对金属-类金属非晶态合金催化剂未来发展的挑战和机遇提出了一些看法。
