Nitrogen oxides (NOx) produced by the combustion of fossil fuels during the operation of internal combustion engine or power plants have been considered as a source of acid rain. To reduce the amount of NOx in the flue gas, the solution of ammonium carbonate and urea has been used industrially. Ammonium carbonate has been produced through reacting the ammonia and carbon dioxide conventionally. However, this method has drawback for the toxicity of ammonia. Herein, we report the more efficient and environmentally benign method for producing ammonium carbonate-urea solution by catalytic reaction of hydrolysis of urea.
