A series of CrOx-ZrO2-SiO2 (CrZrSi) catalysts was prepared by a "one-pot" template-assisted evaporation-induced self-assembly process. The chromium content varied from 4 to 9 wt.% assuming Cr2O3 stoichiometry. were characterized XRD, SEM-EDX, temperature-programmed reduction (TPR-H2), Raman spectroscopy, and X-ray photoelectron spectroscopy. tested in non-oxidative propane dehydrogenation at 500-600 °C. evolution active sites under the reaction conditions investigated reductive treatment...
The high catalytic efficiency of biomorphic systems can be explained by the unique texture and effect ash impurities (K, Ca).
Abstract The effect of the template nature and modification with MnO x on catalytic efficiency Ce 0.8 Zr 0.2 O 2 (CZ) in oxidation CO (2 vol% 1 He, pulse feeding) soot particles (tight contact between catalyst, TGA/DSC) was analyzed. CZ catalysts were prepared using CTAB sawdust (SD) templates modified Mn (8 wt%) by wet impregnation followed calcination at 400 °С. SEM-EDS, XRD, Raman photoelectron spectroscopy, N adsorption, EPR, TPR-H tests results demonstrated better activity CZ(SD) than...
Copper was incorporated into the Ce-Sn and comparative Ce-Zr oxide supports by one-pot precipitation in presence of CTAB template impregnation templated oxides. The synthesized Cu-Ce-Sn Cu-Ce-Zr catalysts were tested continuous-flow preferential oxidation CO hydrogen excess. tin- zirconium-doped demonstrated better conversion CO2 selectivity than their impregnated counterparts. For tin-modified ternary system that showed best catalytic performance, copper content further optimized....
A mesoporous support based on silica and zirconia (ZS) was used to prepare monometallic 1 wt% Pd/ZS, 10 Fe/ZS, bimetallic FePd/ZS catalysts. The catalysts were characterized by TPR-H2, XRD, SEM-EDS, TEM, AAS, DRIFT spectroscopy of adsorbed CO after H2 reduction in situ tested hydrodechlorination environmental pollutant 4-chlorophelol aqueous solution at 30 °C. catalyst demonstrated an excellent activity, selectivity phenol stability consecutive runs. has exceptional reducibility due the high...
Pd/ZrO2 and Pd/ZrO2SiO2 catalysts prepared by wet impregnation reduced with H2 under mild (30 °C, aqueous suspension) or harsh (320 °C) conditions were compared in the hydrodechlorination of microecotoxicant diclofenac solution at 30 оС. According to TPR XPS data, addition SiO2 support reduces degree metal-support interaction facilitates reduction palladium. Despite lower Pd0 fraction, catalyst was more active batch reactor: after 320 °С, it slightly, reduction, signi cantly (7 times)...
