ABSTRACT:
A novel method of producing ammonia by the reduction of molecular nitrogen is provided using a solid metal oxide catalyst and an organic compound in aqueous medium. Pure gaseous nitrogen or air can be reduced in the dark without using any photoenergy or by a photoassisted reaction which uses solar and/or artificial photoenergy. Substantial yields of ammonia are obtained in the dark without the use of photoenergy while major enhancement in yields is obtained via the photoassisted reaction in comparison to presently known methods.
