Y2O3 supported Ni catalysts were prepared from different Y precursors. The catalysts synthesized via Y4O(OH)9(NO3) and YO(NO3) as precursors exhibit superior activity in CO2 methanation reaction compared to the catalysts prepared by direct impregnation of Y2O3. YO(NO3) acts as a unique matrix to aff...
