The effect of dopant Cu, Fe, Ni or La on the structures and properties of mesoporous Co-Ce-O compound catalysts

Hydrogen production by steam reforming of ethanol over Co3O4/La2O3/CeO2 catalysts synthesized by one-step polymerization method

“…These features are present in all catalysts; as can be seen in the profile of CoCe 4 La, CoCe 8 La and CoCe 12 La, the strong intensity of Co 2p 3/2 component at ca. 779.8 indicates that the surface cobalt is largely present as Co 3 O 4 [63][64][65][66]. These results are consistent with the XRD analysis.…”

“…These features are present in samples CoCe 4 La, CoCe 8 La and CoCe 12 La, meaning that a small part of cobalt oxide is present as CoO [63][64][65][66][67][68][69].…”

Synthesis and characterization of CuO/Ce1−Ti O2 catalysts used for low-temperature CO oxidation

“…In our previous studies [12][13][14], it is found that when surfactants are involved in the precipitation process, much higher surface areas can be obtained. So a modified co-precipitation method was used for the preparation of Ce-Ti-O mixed oxide, in which the surfactant P123 (HO(CH 2 CH 2 O) 20 (CH 2 CH(CH 3 )O) 70 (CH 2 CH 2 O) 20 H) was used as a template.…”

Preparation, characterization and utilization of (Ni:Cu) bimetallic system loaded on zeolites

“…The preparation of the catalyst is an important issue for many recent researches for many applications [1][2][3][4][5][6].…”
