The promotion effect of gold addition to Cu/support catalysts in the methanol synthesis reaction was proved. The formation of an Au-Cu alloy was confirmed by XRD technique. Methanol selectivity increased after gold introduction onto the catalyst surface, which can be explained by the creation of nucleation centers for copper crystallization by metallic gold particles during catalyst reduction.
