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.
