The invention discloses a copper-based alloy catalyst and a preparation method and application thereof. The preparation method of the copper-based alloy catalyst comprises the following steps: mixing and dissolving a copper salt, a metal salt and an ionic liquid in a solvent to prepare a mixed solution, then soaking a porous solid carrier in the obtained mixed solution at 25-100 ℃ for 0.5-5 h, and then heating and drying the obtained solid under the condition of blue light irradiation to obtain a treated solid; and roasting the treated solid for 0.5-12 h at the temperature of 200-900 ℃ in a mixed gas of reducing atmosphere and inert gas to obtain the copper-based alloy catalyst. The invention utilizes the characteristic that metal atoms in the copper alloy react with copper atoms to form a stable structure, thereby improving the stability of the copper-based alloy catalyst on a carrier; the drying treatment uses blue light for irradiation, so that the performance of the catalyst is improved; the roasting process enables the copper-based alloy catalyst to produce a stable structure, and simultaneously exposes active sites, thereby improving the catalytic activity of the catalyst. |
