Fast and exothermic reaction of CO2 and Li3N into C-N-containing solid materials.

The conversion of CO(2) to valuable compounds, which is considered as an effective approach to solve the global warming, represents a great challenge due to the high stability and low reactivity of CO(2). Herein, thermodynamic calculations predicted the feasibility of exothermic reactions between CO(2) and Li(3)N into two important solid materials-carbon nitride and lithium cyanamide. Furthermore, the feasibility was confirmed by experiments, namely, the fast reaction between CO(2) and Li(3)N produced crystal lithium cyanamide and amorphous carbon nitrides. This provides a novel process to control CO(2) emissions.
