Claims30
A method of manufacturing a catalyst product comprising:
- (a) selecting precursors of one or more metal organic complexes, each complex comprising a metal ion and an organic ligand wherein at least one of the metal ions when in the resulting catalyst product is catalytic for an intended application;
- (b) mixing a support material and said metal organic complex precursors in a solvent to form a solution;
- (c) allowing molecules of the metal organic complex precursor to absorb on the surface of the support material;
- (d) irradiating the solution until the metal organic complexes are converted into one or more metal nanoparticles at least one of which form a catalytic nanoparticle product attached to the support material.
