Promotional effect of indium on Cu/SiO2 catalysts for the hydrogenation of dimethyl oxalate to ethylene glycol

CuIn/SiO2 with 1.0 wt% indium shows the best catalytic performance for DMO hydrogenation to EG. The synergistic effect of Cu0–Cu+–CuIn alloy in activating H2 molecules and carbonyl bonds is elucidated.

Effect of the ZnO/SiO2 ratio on the structure and catalytic activity of Cu/SiO2 and Cu/ZnO catalysts in water-containing ester hydrogenation

The appropriate addition of ZnO (5 wt%) and SiO₂ (5 wt%) had a positive effect on Cu/SiO₂ and Cu/ZnO, respectively.

Recent progress in improving the stability of copper-based catalysts for hydrogenation of carbon–oxygen bonds

Five different strategies to enhance the stability of Cu-based catalysts for hydrogenation of C–O bonds are summarized in this review.

Dynamic redox cycle of Cu0 and Cu+ over Cu/SiO2 catalyst in ester hydrogenation

Esters can oxidize Cu⁰ to Cu⁺ and the obtained Cu⁺ can be reduced back to Cu⁰ by H₂ under reaction conditions. Cu⁰ and Cu⁺ are in a dynamic cycle during ester hydrogenation.

Remarkable crystal phase effect of Cu/TiO2catalysts on the selective hydrogenation of dimethyl oxalate

Crystal phase of titania support plays an important role in catalytic hydrogenation of dimethyl oxalate. Optimized catalytic performance was achieved for the Cu/P25 due to the intimate metal support interaction.

Structured Pd–Au/Cu-fiber catalyst for gas-phase hydrogenolysis of dimethyl oxalate to ethylene glycol

A structured Pd–Au/Cu-fiber with a ternary Pd–Au–Cu⁺ complex is active, selective and stable for the gas-phase hydrogenolysis of dimethyl oxalate to ethylene glycol.

Highly selective one-pot continuous synthesis of 2-methoxyethanol via hydrogenation of dimethyl oxalate on Cu/ZrO2 catalysts with balanced acid sites

The distribution of 2-methoxyethanol and ethylene glycol can be controlled by regulating the surface acidity of copper based zirconia catalysts for hydrogenation of dimethyl oxalate. The yield of 2-methoxyethanol can reach 68% due to the synergistic effect of the surface acid site and active copper site.

Efficient hydrogenation of aromatic aldehydes to corresponding benzyl alcohols over Ni–B/MIL-101

Ni–B amorphous alloy particles incorporated onto MIL-101 were prepared by a simple reduction impregnation method, and exhibited excellent catalytic activities for liquid-phase chemoselective hydrogenation of aromatic aldehydes to corresponding benzyl alcohols.
