Formation of Highly Dispersed Rhodium Particles by Chemical and Photochemical Reduction
Nanometer-sized metal particles have been prepared by chemical and photochemical reduction of homogeneous solutions of metal-organic rhodium(I) compounds. Reduction of [(COD)RhCl]2 with LiBEt3H in THF resulted in...
