This Perspective discusses tandem catalytic paradigms for sustainable CO₂ conversion, which offer advantages over single-functional catalysts. Tandem catalysis involves multifunctional catalysts in a single reactor or multiple catalysts in separate reactors, enabling the production of complex products from CO₂. Tandem processes can simplify intermediate product separation, reduce safety risks, and enhance catalytic performance by coupling distinct reactions. They are particularly useful for producing longer-chain hydrocarbons, complex molecules, and oxygenates that are difficult to obtain through direct CO₂ conversion. Tandem catalysis can be implemented in both thermocatalytic and electrocatalytic processes, with examples including the conversion of CO₂ and ethane to value-added products. Tandem reactors allow for the optimization of reaction conditions and catalyst compositions, and can be used to produce a wide range of products, including BTEX aromatics, oxygenates, and hydrocarbons. Tandem electrocatalytic processes are also explored, with examples including the production of ethylene and higher alcohols. Tandem EC–TC and TC–EC reactors are also discussed, with examples of their application in producing complex products. The integration of various catalytic approaches, including photocatalysis, biocatalysis, and plasma-assisted catalysis, is also highlighted. The potential of tandem processes for sustainable CO₂ conversion is emphasized, with opportunities for further research and development in this area.This Perspective discusses tandem catalytic paradigms for sustainable CO₂ conversion, which offer advantages over single-functional catalysts.
