In situ Studies of Alloy Formation on a Pd/Ga2O3 Methanol Steam Reforming Catalyst
Methanol steam reforming is a promising reaction in terms of hydrogen production for use in PEM fuel cells. Catalyst research has focused mainly on Cu/ZnO formulations, because of their superior selectivity to CO2 and H2. The common byproduct CO is problematic due to its poisoning effect on the anode of a downstream fuel cell. Some years ago it was shown that palladium supported on certain redu...
متن کاملZnO Nanowire-supported Ag Catalyst for Methanol Steam Reforming
Alternative energy sources, such as various fuel cell technologies, have attracted intense attention due to their high efficiency and low emissions of pollutants. Methanol, with its high hydrogen/carbon ratio, low sulfur content and the absence of carbon–carbon bonds, has been identified as a highly suitable source for onboard production of hydrogen [1]. Among several reactions for converting m...
متن کاملEffect of Pt on Zn-Free Cu-Al Catalysts for Methanol Steam Reforming to Produce Hydrogen
Steam reforming of methanol can be considered as an attractive reaction aiming at hydrogen production for PEM fuel cells. Although Cu/Al-contained catalysts are considerably evaluated in this reaction, further evaluation is essential to evaluate the impact of some promoters like Pt in order to find a comprehensively optimized catalyst. Pt promoter is employed with different methods in this ...
متن کاملPd/Ga2O3 methanol steam reforming catalysts: Part II: Catalytic selectivity
Structure, morphology and composition of two Pd/Ga2O3 methanol steam reforming catalysts were correlated with the associated activity and selectivity changes in the methanol steam reforming reaction and linked to studies on pure Ga2O3 supports. For both systems, that are, a Pd/Ga2O3 thin film model catalyst and a powder-supported Pd catalyst, we identified a temperature range in which the reduc...
متن کاملMethanol steam reforming; Effects of various metal oxides on the properties of a Cu-based catalyst
Ternary Cu/ZnO/metal oxide catalysts are prepared through the co-precipitation method under strict control of parameters like pH, calcination conditions, and precipitation temperature in a systematic manner. The metal oxides applied in this study consist of Al2O3, ZrO2, La2O3 and Ce2O3. The distinction of this work in comparison with similar research is a comprehensive investigatation of the ca...
