Origin of Pd-Cu bimetallic effect for synergetic promotion of methanol formation from CO2 hydrogenation

[Display omitted] •The selective promotion of CH3OH in CO2 hydrogenation correlates to Pd-Cu alloy content.•Pd-Cu combination shifts adsorption towards weakly-bonded H2 and CO2.•Weakly-bonded H2 and CO2 species over Pd-Cu appear to correlate with CH3OH promotion.•DFT study rationalizes CO2 adsorptio...
