[EN] The modification of CueZn catalysts with low amount of Al and Ga (AlþGa ¼ 3%) was investigated and data corresponding to its influence on the decomposition of the calcined precursors and on the nanomorphology and surface concentration of reduced catalysts were presented in this contribution. The data presented here are supplementary material of the catalysts presented in the research article “Structure and activity of Cu/ZnO catalysts comodified with aluminium and gallium for methanol synthesis” published
in Catalysis Today [1]., The present investigation was performed within the research program CTQ2016-76505-C3-1 supported by the Spanish Ministry of Science, Innovation and Universities. Elena Millán would like to acknowledge the FPI programme from Spanish Ministry of Science, Innovation and Universities for the research grant., Peer reviewed
