The co-catalyst chemical composition was modified by replacing palladium atoms with copper. The preparation method renders alloyed particles with a primary particle size in the 5–6 nm interval. A Pd:Cu 3:1 ratio promotes strongly the activity of the noble metal. According to the quantum efficiency parameter, the Pd:Cu 3:1 alloy increases by ca. 2 the activity of the monometallic Pd counterpart. The analysis of the photoactivity points out that alloying does not affect positively charge recombination and handling.engAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/journal articlehttps://doi.org/10.1016/j.cattod.2023.114280open access615:54615.31PhotocatalysisHydrogenMethanol:WaterQuantum efficiencyPd-Cu alloysFarmacia3209 Farmacología
