Procedure

The precursor for the NiO gel is nickel nitrate dissolved in ethanol or isopropanol. The precursor for Y2O3 is either yttrium nitrate or yttrium isopropoxide. Yttrium nitrate solution is prepared by dissolving Y2O3 in nitric acid solution. The solution is then evaporated to dryness to prepare yttrium nitrate which is then dissolved in ethanol or isopropanol at a pH of about 3. Alternatively, yttrium sol is prepared by dissolving yttrium isopropoxide in isopropanol.
