Cu-ZnO-Al2O3 catalysts for the low-temperature water-gas shift reaction were prepared using methods of direct and reverse coprecipitation. The catalysts obtained were characterized by DRX, TPR, XPS, N2O chemisorption, ...

Monte Carlo simulations for the productivity and order of the PROX/copper-ceria catalyst reaction with different superficial %Cu are made. The results are correlated with the behavior of the different surface species (CO, ...

Copper nanoparticles (CuNPs) supported on ZnO are a highly active and selective heterogeneous catalyst for the N-arylation of cyclic and acyclic amides (Golberg coupling). The reaction conditions are mild, featuring K3PO4 ...

Acetaldehyde is an important chemical commodity and a building block for producing several other high-value products in the chemical industry. This has motivated the search for suitable, efficient, stable, and selective ...

Lacunary [PCuW11O39]5− species modified with chiral bis(oxazoline) leads to very poor results as catalyst in theenantioselective cyclopropanation, in contrast with the Cu-bis(oxazoline) complex exchanged on the Keggin[PW12O40]3− ...

Two wet-proofed catalysts were prepared by subsequent coating steps with polytetrafluoroethylene fibers over a CuO/γAl2O3 catalyst. They were tested for the oxidation of phenol solutions in a semi-batch reactor. Phenol ...

A large variety of catalytic systems have been studied for the catalytic wet air oxidation of phenolic solutions. Most of them show good activity, but serious stability problems. In this contribution, stability studies ...

Copper nanoparticles (CuNPs) supported on ZnO are highly active and selective heterogeneous catalyst for the N-arylation of cyclic and acyclic amides (Golberg coupling). The reaction conditions are mild, featuring K3PO4 ...

The liquid phase hydrogenation of cinnamaldehyde was studied at 393 K and 10 bar on Cu-based catalysts containing about 12 wt.% of copper. Cu/SiO 2 was prepared by incipient wetness impregnation while Cu-Al, Cu-Zn-Al, and ...
