Characterization and oxidation states of Cu and Pd in Pd–CuO/ZnO/ZrO2 catalysts for hydrogen production by methanol partial oxidation

Nanocomposite membranes of polyetherimide nanostructured with palladium particles: Processing route, morphology and functional properties

“…We determined on one hand the percentages of Pd and O species present at the film surface and compared on the other hand the binding energy of Pd3p3/2 that is characteristic of the palladium environment in our films with those of palladium involved in PdO and in pure Pd metal, respectively. These last binding energy values were taken from the literature [44,45]. The results are presented in Table 1.…”

Catalytic Partial Oxidation of Methanol and Ethanol for Hydrogen Generation

“…[114] Another way to maintain the reactivity is through catalyst engineering. CuZnAl-layered double hydroxides derived Cu-Zn/Al 2 O 3 [126] and complex composites [127][128][129] (e.g., CuO/ZnO/ZrO 2 /Pd) made by co-precipitation and combustion techniques (e.g., volume combustion synthesis) were fabricated to enhance the interactions between copper and additives.…”

Catalytic partial oxidation of methanol over Au–Pd bimetallic catalysts: a comparative study of SBA-16, SBA-16-CeO2, and CeO2 as supports

“…However, the main disadvantage of these catalysts is the formation of considerable amounts of CO, which is a known poisonous component for the PEMFC anode. Recently, numerous attempts have been made to modify the catalytic performances of Pd catalysts by the addition of Au, Cu, Zn, and so on [12][13][14]. Among these additives, Au has attracted great attention, due to its excellent catalytic activity for CO oxidation at low temperature [15,16].…”
