Abstract: Proposed is a catalyst complex having high activity for carbon dioxide conversion reaction that converts carbon dioxide to useful compounds through reaction of carbon dioxide and hydrocarbon containing at least one hydroxyl group, and a carbon dioxide conversion process using the same, wherein the catalyst complex includes, as an active metal in the catalyst complex, at least one of noble metals and at least one of transition metals other than noble metals, thereby having high activity for the carbon dioxide conversion reaction.

Abstract: Proposed is a high-yield simultaneous conversion method for a hydrogen source and a carbon dioxide source. The method significantly increases a yield of a formate through conversion of carbon dioxide. To this end, a carbon dioxide source and a hydrocarbon containing one or more hydroxy groups undergo a simultaneous conversion reaction in the presence of a solvent containing one or more alcohols and having a pH of 10 to 14.

Abstract: Proposed is a two-pot-two-step simultaneous conversion system for carbon dioxide and a hydrocarbon containing at least one hydroxy group and a method thereof. The system integrates a process of producing a metal salt that is a dehydrogenated form of the hydrocarbon, hydrogen, and water by reacting a hydrocarbon containing at least one hydroxy group in the presence of water and a metal oxalate, and a process of converting carbon dioxide or carbon dioxide-derived carbonate into formate by hydrogenation, thereby increasing energy efficiency while maintaining a higher hydrocarbon conversion rate and a higher carbon dioxide conversion rate than the one-pot conversion system for hydrocarbon and carbon dioxide.
