ZrO(2), gamma-Al(2)O(3) and ZrO(2)/gamma-Al(2)O(3)-supported copper catalysts have been prepared, each with three different copper loads (1, 2 and 5 wt%), by the impregnation method. The catalysts were characterized by ...

The ethanol conversion into ethyl acetate is a very important reaction, in economic and scientific fields. In the context of science, the propose of this work was to evaluate the activity of Au and Cu catalysts supported ...

The nanoparticles of CuFe2O4, with spinel structure, supported over ZrO2 and sulphated ZrO2, were obtained by the precursor citrate route. The supported catalysts, containing a ferrite/support ratio of 30%, were thermally ...

In both industry and academia the interest in biomass conversions into manufactured products has grown rapidly in recent years. Various products can be obtained from alcohol chemistry such as acetaldehyde, ethyl acetate, ...

The effect of the support, Al2O3, ZrO2, and SiO2, on the activity for CO oxidation of a series of CuO and CeO2 monometallic and bimetallic catalysts was studied. The catalysts were prepared by coimpregnation of the support ...

The activity in the WGS reaction of Cu/ZrO2 catalysts prepared by a method of refluxing in an aqueous NH4OH solution is studied. It is shown that at 3% Cu load the methods of impregnation over monoclinic or tetragonal ZrO2 ...

The origin and influence of active sites on supported copper catalysts, and their catalytic properties for ethanol conversion, were investigated using Cu/SiO2, Cu2O/SiO2, and Cu/ZrO2. Diffuse reflectance infrared Fourier ...
