Kourosh Kalantar-Zadeh The University of Sydney Green reactions using liquid metals 【Abstract】 Low-melting-point liquid metals possess less studied chemistry and physics. While these molten metals offer extraordinary potential for catalysis and enabling low-energy reactions, our understanding of their capabilities remains relatively rudimentary, and their primary applications are largely constrained to specific fields. This presentation introduces innovative concepts showcasing the contributions of liquid metals to the realm of eco-friendly reactions and catalysis. The discussion encompasses the synergistic fusion of metallurgy with liquid metals to harness distinctive advantages for creating highly reactive metallic compounds in liquid states. Emphasis is placed on the utilisation of alloying, capitalising on interfacial layering, surface competition or crystallisation of added components, or exploiting the active surface of liquid metals as reaction media. The presentation explores how liquid metals can serve as a platform for generating highly reactive species, facilitating reactions at reduced energy levels, and functioning as electrochemical catalysts and converters. Furthermore, the potential transformative impact of liquid metal systems in the creation of solid catalysts and dynamic reconfiguration of surfaces for liquid catalysis, driven by high entropy, is discussed. All of these aspects are poised to significantly influence future advancements in chemical and environmental technologies. 目前低熔点液态金属的化学和物理研究相对较少。虽然这些熔融金属在催化和实现低能反应方面具有非凡的潜力，但我们对它们特性的了解仍处于初级阶段，从而它们的主要应用在很大程度上限于特定领域。本次报告将介绍一些创新性概念，以展示液态金属在环境友好型反应和催化领域的贡献。讨论包含利用冶金与液态金属协同作用的独特优势，在液态环境中创造高活性金属化合物。讨论的重点将放在合金的利用，充分利用分层界面，表面竞争或异质结晶，或利用液态金属的活性表面作为反应介质。该报告探讨了如何利用液态金属作为产生高活性物质的平台，降低反应能，以及作为电化学催化剂和转换器等功能。除此之外，报告将讨论液态金属系统（由高熵驱动）在固体催化剂的创造和液体催化表面动态重构方面潜在的变革性影响。所有这些方面都将对未来化学和环境技术的发展产生重大影响。 【BIOGRAPHY】 Kourosh Kalantar-Zadeh is a Professor and Head of School of Chemical and Biomolecular Engineering at the University of Sydney.
