Abstract: [Display omitted] • TiCe and TiZr binary supports boost CH 3 OH formation and selectivity than single one. • Lowering temperature enhances CH 3 OH selectivity over Pd-Cu/ Ti x Zr 1- x O 2 to 58.8 %. • Incorporation of Zr into Ti support in Pd-Cu/Ti x Zr 1- x O 2 enhances Pd-Cu alloy. • Ti-Zr binary supports successfully attain moderate metal support interaction. Binary supports TiO 2 -CeO 2 and TiO 2 -ZrO 2 improved CH 3 OH formation and selectivity effectively, but with little effect on CO 2 conversion. Pd-Cu/Ti 0.8 Ce 0.2 O 2 enhanced CH 3 OH formation by ca. 46 % comparing to Pd-Cu/TiO 2 -C. Pd-Cu/Ti 0.1 Zr 0.9 O 2 exhibited the highest catalytic performance: CH 3 OH formation rate was 0.62 μmol g-cat−1s−1, which was enhanced by 121 %, 51 %, and 51 % in comparison to Pd-Cu/TiO 2 -C, Pd-Cu/ZrO 2 -C, and Pd-Cu/Ti 0.8 Ce 0.2 O 2 , respectively. More interestingly, lowering temperature from 523 K to 493 K further enhanced CH 3 OH selectivity from 44.6%–58.8%. Binary supports significantly increased surface area. Unexpectedly, it did not improve H 2 reduction for Pd-Cu/Ti x Zr 1- x O 2 in H 2 -TPR, but decreased H 2 uptake to stoichiometric level, implying SMSI was adjusted to moderate state. However, the excessive H 2 uptake further increased for Pd-Cu/Ti x Ce 1- x O 2 , indicating unalleviated SMSI. Furthermore, Pd-Cu alloy formation was improved in Pd-Cu/Ti x Zr 1- x O 2 , which was favorable for CH 3 OH synthesis. Binary supports also improved CO 2 adsorptive behavior towards weakly-bonded species, contributing to better performance. [ABSTRACT FROM AUTHOR]
