Abstract
The invention concerns a catalyst for the low energy manufacture of ammonia; a process for manufacturing said catalyst; and a process for low energy manufacture of ammonia comprising the use of said catalyst.
Claims26
An atomic metal catalyst, said catalyst comprising a plurality of metal atom clusters supported on the surface of a solid substrate, wherein each metal atom cluster independently comprises from about 1 to about 500 metal atoms.
A method for producing ammonia via heterogeneous catalysis, the method comprising:
- (i) disposing in a reactor a catalyst bed comprising an atomic metal catalyst;
- (ii) passing nitrogen (N2) and hydrogen (H2) over said catalyst bed;
- (iii) obtaining a product stream comprising ammonia (NH3);
- wherein the atomic metal catalyst comprises a plurality of metal atom clusters supported on the surface of a solid substrate, wherein each metal atom cluster independently consists of from 1 to 500 metal atoms, wherein the number of metal atoms is determined by STEM;
- wherein the said substrate is a silicon or carbon-based material, an oxide, a hydride, a nitride or a MXene;
- wherein each of said metal atom clusters comprises platinum (Pt), molybdenum (Mo), rhenium (Re) cobalt (Co), ruthenium (Ru), rhodium (Rh) and iron (Fe).”
