The liquid metal catalysts present catalytic systems with dynamic interfaces and mobile active atoms. The origin of catalytic performance in such a liquid phase system has remained elusive for the rational design of efficient liquid metal catalysts. A detailed understanding of the atomistic structure and fundamental chemistry at the interface of liquid metals would optimize materials for catalytic reactions. However, there has been limited success in fully addressing the atomic-level structural arrays of liquid metal catalysts and their reaction mechanisms in catalysis. Recently, liquid metals have emerged as catalysts with advantageous characteristics for a wide range of applications. This review explores the fundamental properties and reaction chemistry of liquid metal catalysts. Recent advances in liquid metal research are outlined with respect to thermal, electrochemical, and other catalysis. Considering available density functional theory calculations and ab initio molecular dynamics simulations, we highlight the exceptional capabilities of molecular simulation approaches in characterizing the surface structures, electronic properties, and catalytic properties of liquid metals and alloys on the atomic level. Furthermore, we discuss the current simulation challenges for liquid metal systems and outline how molecular simulation approaches can contribute to developing liquid metals in catalysis.

“…By virtue of this, high-entropy alloy nanoparticles with a wide range of elements were successfully prepared under mild conditions (Figure 7a). 56 The low melting point of liquid metal makes it accessible for fabricating high-value functional structures toward efficient catalysis. Taking advantage of this, a metal foam with a conducting core and catalytical semiconducting surface was successfully obtained based on the Field's metal (eutectic InBiSn alloy), which reduced the reaction temperature from 600−1000 to 200 °C.…”

Catalysts serve pivotal roles in facilitating the development of sustainable energy systems on a global scale. Liquid metal usually refers to metal that is liquid below 330 °C, also known as low melting point metal. Liquid metal has emerged as an intriguing catalyst due to its commendable electrical conductivity, favorable fluidity, solubility in metals, phase transition capabilities, and modifiable oxide surface, thereby presenting a plethora of prospects for diverse catalytic reactions. In this Perspective, we elucidate the four primary merits of liquid metal catalysts: resistance to coking, the ability to tune elemental composition, the potential for structural transformation, and the capacity to inhibit coalescence. In light of this, a comprehensive summary is presented on the research advancements pertaining to liquid metal in methane pyrolysis, alkane dehydrogenation, carbon dioxide reduction, alcohol oxidation, and various other catalytic reactions. Finally, the challenges and prospects of liquid metal catalysts are elucidated.
