Abstract
AbstractHighly dispersed silica‐supported Ni particles have been prepared by cation exchange from a nickel nitrate solution in NH3 and H2 reduction at 275 K. The dispersion is more homogeneous than for samples prepared by classical im?regnation and the particle size is found to be 1.8 nm with a slight discrepancy in the values measured by TEM, FMR and magnetic susceptibility.
