Co3O4 hollow nanotubes for the catalytic oxidation of C2-chlorinated VOCs
(Elsevier, 2023-04-07)
Structured Co3O4 catalysts with a hollow nanotube morphology were prepared by several synthesis routes based on the Kirkendall effect. The resulting samples were kinetically evaluated in the gas-phase oxidation of vinyl ...
Optimisation of bimetallic Co-Ni supported catalysts for oxidation of methane in natural gas vehicles
(Elsevier, 2020-11-21)
This work deals with the extensive study of supported bimetallic Co-Ni catalysts for the complete oxidation of methane. The simultaneous incorporation of nickel and cobalt was found to enhance the redox properties by ...
Catalytic removal of chlorinated compounds over ordered mesoporous cobalt oxides synthesised by hard-templating
(Elsevier, 2017-09-28)
This work evaluates the catalytic behaviour of a series of mesoporous bulk cobalt oxide prepared by hard-templating using SBA-15, SBA-16 and SBA-3. In addition, a bulk catalyst obtained by silica aquagel confined precipitation ...
On the beneficial effect of MgO promoter on the performance of Co3O4/Al2O3 catalysts for combustion of dilute methane
(Elsevier, 2019-05-30)
The present work deals with the analysis of a series of cobalt catalysts (20 and 30%wt.Co) supported on alumina modified with MgO (7–18%wt.Mg with respect to the support) for the combustion of dilute methane. Both modified ...
Oxidation of lean methane over cobalt catalysts supported on ceria/alumina
(Elsevier, 2019-12-23)
Cobalt (30 %wt.) oxide catalysts supported over ceria-modified (3–18 %wt.) alumina supports were examined for the combustion of lean methane. The prepared samples were characterised by wavelength dispersive X-ray fluorescence, ...
Catalytic Oxidation of Vinyl Chloride over SrCO3-Co3O4 Catalysts: Effect of the Sr:Co Molar Ratio
(The Italian Association of Chemical Engineering (AIDIC), 2023-05-30)
Co3O4 catalysts modified with SrCO3 with various Sr:Co molar ratios were synthesized by a co-precipitation method and their catalytic behavior was examined for the gas-phase oxidation of vinyl chloride. The physicalchemical ...
Influence of the calcination temperature on the activity of hydroxyapatite-supported palladium catalyst in the methane oxidation reaction
(Elsevier, 2020-06-26)
In the present study, a series of four hydroxyapatite (HAP) supported palladium samples, with a Pd loading close to 0.5 %, obtained through their calcination at 773, 873, 973, or 1073 K has been investigated. These samples ...
Bimetallic Ni-Co/Al2O3 Catalysts Derived from Aluminate Spinels for Dry Reforming of Methane
(The Italian Association of Chemical Engineering (AIDIC), 2023-04-20)
Five Ni-Co/Al2O3 catalysts for dry reforming of methane were obtained by high-temperature reduction of mixed Ni-Co spinel aluminates (NixCo1-xAl2O4) synthesised by a precipitation route. The aim of the study was to determine ...
Pd supported catalyst for gas-phase 1,2-dichloroethane abatement: Efficiency and high selectivity towards oxygenated products
(Elsevier, 2017-08-12)
Hydroxyapatite (HAP) support has been synthesised and impregnated with different amounts of Pd. The prepared Pd/HAP catalysts have been thoroughly characterised by BET, XRD, TEM, UV–visible–NIR, FTIR, XPS, CO2-TPD and NH ...
Behaviour of Rh supported on hydroxyapatite catalysts in partial oxidation and steam reforming of methane: On the role of the speciation of the Rh particles
(Elsevier, 2018-03-04)
Rh/hydroxyapatite samples were prepared by impregnation and investigated for the partial oxidation (POM) and steam reforming (SRM) of methane. The catalysts were analysed by BET, XRD, DRS, XPS, H 2 -TPR, TEM, H2 chemisorption, ...
