Adsorptive and Catalytic Properties of Alumina-Supported Pd–Mo Catalysts

Oxidative Steam Reforming of Ethanol over Ni–Cu/SiO2, Rh/Al2O3 and Ir/CeO2: Effect of Metal and Support on Reaction Mechanism

“…6, along with carbon yields in Table 4. The observed trends are in general agreement with TPD literature data describing ethanol decomposition on Ni based catalysts, though the specificity of the present catalyst deserves to be outlined [20,21,[37][38][39][40].…”

“…In agreement with IR data, the release of acetaldehyde from ethoxy species was also revealed around 110°C with a carbon yield of 0.54% followed by the release of CO, CO 2 and CH 4 . The slight desorption of H 2 in this low temperature range is in line with the decomposition of ethoxy species [37][38][39]. Cordi and Falconer [38] suggested that the ethoxy species adsorbed on Pd sites decomposes at lower temperature.…”

Structured catalyst of Pd/ZnO on sintered metal fibers for 2-methyl-3-butyn-2-ol selective hydrogenation

“…Molybdenum is also known to decrease hydrogen and olefin adsorption strength on Pt group metals, thus influencing the selectivity and activity of hydrogenation reactions [70]. However, in the present study, it was not possible to distinguish between this effect and the size sensitivity of MBY hydrogenation.…”

Partial oxidation of ethanol on Ru/Y2O3 and Pd/Y2O3 catalysts for hydrogen production

“…However, the oxidation of ethoxy species is not probably the only reaction occurring at this temperature. Several works have reported the appearance of CO, CH 4 and H 2 at the low temperature region during FTIR and TPD analysis of adsorbed ethanol, which was attributed to the decomposition of ethoxy species [26,40,[46][47][48]. This result revealed that the ethoxy species were also decomposed at this temperature.…”
