Cordierite monoliths washcoated with MnCoCe(CP), Co(I)/ZrO2 and Co(I)/CeO2 catalysts were prepared and studied for the CO preferential oxidation (COPrOx) reaction. Among them, the MnCoCe/M system presented the best CO ...

In this work, catalysts based oncobalt supported on ZrO2 and CeO2, and CoCeMnOx were studiedfor the CO preferential oxidation (COPrOx) in rich-hydrogen stream able to feedfuel cells. Among them, the CoCeMnOx formulation ...

Co, Ce and Co-Ce nanofibers were synthesized by the electrospinning method. To obtain mixed fibers, Co was incorporated in two ways: one step synthesis and sequential synthesis. Nanofibers were applied to two reactions: ...

Cordierite monoliths washcoated with Co/CeO2 catalysts prepared from different methods were studied for the CO preferential oxidation reaction. Powder catalysts were also studied for the sake of comparison and in order to ...

Mn-Co-Ce mixed oxides are active and selective catalysts for the CO preferential oxidation (COPROX), which is a promising process for the purification of hydrogen streams. In this work, we report a careful spectroscopic ...

La(1-x)Ce(x)NiO(3) perovskites have been prepared, characterized by XRD. TPR and surface area and tested as catalysts for CO-PROx, with a feed of 2.5% CO, 5% O(2), 33% H(2) and N(2) to 100%. The samples exhibited an XRD ...

In the present work, we report the synthesis and characterization of two new heterometallic coordination polymers based on Ce-III and containing Co-II or Cu-II cations, assembled by the bifunctional ligand 1H-imidazole-4 ...

Microreactors based on Cu, Ce oxides dispersed onto zeolite films grown on brass microgrids were developed. Secondary synthesis conditions were regulated in order to obtain thin, homogeneous and adherent coatings of mordenite ...
