Fundamentals, Applications, and Perspectives of Liquid Metals in Catalysis: An Overview of Molecular Simulations

“…78 During the reaction, the dissolved Li metal migrated to the liquid−gas interface and instigated the dissociation of CO 2 into carbon and oxygen, while the Li content underwent an oxidation process. 79 Another investigation unveiled similar reaction mechanisms employing an innovative Mg−Ga liquid metal alloy to convert CO 2 into solid carbon. Initially, the Mg component diffused to the Mg−Ga alloy surface, facilitating the conversion of CO 2 to carbon, with the simultaneous oxidation of Mg to MgO.…”

“…A recent study by Ye et al demonstrated a controllable Li–Ga liquid metal alloy system for the reduction of CO 2 into solid carbonaceous materials at low temperatures. During the reaction, the dissolved Li metal migrated to the liquid–gas interface and instigated the dissociation of CO 2 into carbon and oxygen, while the Li content underwent an oxidation process . Another investigation unveiled similar reaction mechanisms employing an innovative Mg–Ga liquid metal alloy to convert CO 2 into solid carbon.…”

“…Beyond the use of liquid metals in electrocatalytic CO 2 reduction to produce solid carbon, the direct conversion of CO 2 into solid carbon using Ga-based liquid metal alloys has recently emerged as a significant area of research interest. , One pioneering study by Zuraiqi et al investigated the direct decomposition of CO 2 to yield solid carbon using a eutectic of gallium and indium (EGaIn) as a liquid metal alloy. The unique characteristics of the liquid metal, such as its low carbon solubility and remarkable resistance to coking, facilitated enhanced separation and collection of produced carbon .…”

Passivation-Free, Liquid-Metal-Based Electrosynthesis of Aluminum Metal–Organic Frameworks Mediated by Light Metal Activation

“…Liquid metals are a genre of metals with low melting points, which are commonly referred to the family of post transition metals, e.g., gallium (Ga), indium (In), and bismuth (Bi). − Unlike conventional solid metals, liquid metals, especially Ga, can remain in the liquid state at close to room temperature and can be utilized for alloying other metals into liquid-state mixtures. − The electron-rich interface and liquid state of liquid metals endow great potential for facilitating chemical reactions and can be applied for the synthesis of miscellaneous functional materials. ,− …”

Liquid-Metal Solvents for Designing Hierarchical Nanoporous Metals at Low Temperatures

“…As a result, a number of dynamic processes such as dissolution, interdiffusion, and intermetallic formation can take place at the liquid–solid interface, leading to structural reconstruction and emergent phases. At or near room temperatures, liquid-metal gallium (Ga) and Ga-based alloys form intermetallic phases with many metals, particularly transition metals. , This liquid-metal-based intermetallic crystal growth method could be a promising route for designing bimetallic or multimetallic structures that are highly desirable for diverse applications such as catalysis and sensing. − …”
