Energy efficient CO₂ utilization is critical for climate change mitigation and a smooth transition to renewable technologies. State-of-the-art research efforts show a growing interest in non-noble metal catalyst design paired with electrochemical and mechanical techniques. An emerging reaction medium, catalyst, and reactant is liquid metal (LM). First, LM colloids show remarkable selectivity and catalytic efficiency. Triboelectric charging supports the reactant-catalyst contact and product detachment from the catalyst surface. Secondly, LM electrodes can improve safety, conversion efficiency and rate performance compared to solid electrodes. The presence of a liquid-liquid interface improves mass transport and stability. Finally, fully LM media is another possible solution to produce hydrocarbons and conductor materials with high mechanical performance. The focus of LM studies is currently on alloy catalyst and co-catalyst engineering. Gallium technologies are accessible due to the low price point and operating temperatures, as Ga is liquid near room temperature. Gallium dominates the production of solid carbon; future trends for alloy systems may also include Ni, Fe and Ce, which alternatively promote CO formation.
