A silica decoration methodology of Ni−Zn alloy was applied to Ni−Fe and Ni−Ga alloy to improve their activities on acetylene hydrogenation. Ni−Fe and Ni−Ga alloys were decorated by additional SiOx species by impregnation with an ethanol solution of triphenylsilanol (C18H16OSi). The results show that the degree of alloying and the size of Ni−Fe did not change as well as Ni−Ga. The catalytic activity towards Si−Ni−Fe/SiO2 and Si−Ni−Ga/SiO2 was successfully enhanced compared to the undecorated which was similar to the result that has been reported for Si−Ni−Zn/SiO2. This result proved that silica decoration methodology was effective in the improvement of Ni alloy-based catalysts. © 2023 American Institute of Physics Inc.. All rights reserved.
