Direct Synthesis of Formamide from CO₂ and H₂O with Nickel-Iron Nitride Heterostructures under Mild Hydrothermal Conditions.

ABSTRACT: Formamide can serve as a key building block for the synthesis of organic molecules relevant to premetabolic processes. Natural pathways for its synthesis from CO₂ under early earth conditions are lacking. Here, we report the thermocatalytic conversion of CO₂ and H₂O to formate and formamide over Ni-Fe nitride heterostructures in the absence of synthetic H₂ and N₂ under mild hydrothermal conditions. While water molecules act as both a solvent and hydrogen source, metal nitrides serve as nitrogen sources to produce formamide in the temperature range of 25-100 °C under 5-50 bar. Longer reaction times promote the C-C bond coupling and formation of acetate and acetamide as additional products. Besides liquid products, methane and ethane are
