An analysis of the first steps of phenol adsorption-oxidation over coprecipitated Mn-Ce catalysts: a DRIFTS study
(Springer, 2012-06-23)
A series of Mn–Ce(M) solids (M = K or Na), with molar ratios 100–0, 50–50 and 0–100 were prepared by co-precipitation of manganese and cerium nitrate from NaOH or KOH solutions at pH = 11. In addition, part of the solids ...

Co/ZrO2, Co/CeO2 and MnCoCe structured catalysts for COPrOx
(Elsevier, 2013-11)
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 ...
