Functional nanostructured catalysts based on the niobates to the dry methane reforming and ethylene homologation reactions
(2013-01-01)
Catalytic activity and selectivity of niobate-based nanostructured materials were investigated. Dry methane reforming (DMR) and ethylene homologation reaction (EHR) were selected as test reactions. KSr 2Nb5O15, Sr2NaNb5O ...

The role of the coprecipitation sequence of salt precursors on the genesis of Cu-ZnO-Al2O3 catalysts. synthesis, characterization and activity for low temperature shift reaction
(1998-06)
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, ...
Au/TiO2 supported on ferritic stainless steel monoliths as CO oxidation catalysts
(Elsevier, 2013-01)
Metallic supported structured catalysts were obtained by washcoating AluchromYHf monoliths with an Au/TiO2 catalyst. The powder catalyst was synthesized by DAE (direct anionic exchange) method. Using this catalyst, a stable ...
Synthesis of spherical structured catalysts by dip-coating: Application to n-butane dehydrogenation
(John Wiley & Sons Inc, 2017-06)
This work analyzes the deposition conditions of thin layers of γ-Al2O3 by dip-coating on a spherical substrate of α-Al2O3 spheres. Results showed that under controlled deposition conditions, a structured support of α-Al2O3 ...
Removal of nitrate from drinking water by using PdCu structured catalysts based on cordierite monoliths
(Brazilian Society of Chemical Engineering, 2019-06)
Structured catalysts were prepared, characterized and evaluated in NO3 - removal from drinking water. Different suspensions containing a previously optimized PdCu/5wt% ZrO2-Al2O3 powder catalyst (hereinafter PdCu/5ZAp) ...
Effect of the ZrO2 phase on the structure and behavior of supported Cu catalysts for ethanol conversion
(2013-08-06)
The effect of amorphous (am-), monoclinic (m-), and tetragonal (t-) ZrO2 phase on the physicochemical and catalytic properties of supported Cu catalysts for ethanol conversion was studied. The electronic parameters of ...
