“…The promotion effect was explained by the alloy formation. In previous work, we confirmed the promotion effect of palladium on the reactivity results of copper‐ and nickel‐ supported catalysts in steam reforming of methanol. The catalytic and physicochemical properties of monometallic copper and various bimetallic Ru–Cu, Rh–Cu, Ag–Cu, and Ir–Cu catalysts supported on binary oxide ZrO 2 –Al 2 O 3 or ZnO‐Al 2 O 3 were studied in oxy‐steam reforming of methanol reaction .…”

Monometallic Ni and bimetallic Pd–Ni catalysts supported on mono‐SnO2 and SnO2–Al2O3 binary oxide are prepared using a wet impregnation and subsequent impregnation method. The catalysts are tested in oxy‐steam reforming of methanol (OSRM) and characterized. The activity measurements show that palladium‐promoted nickel catalysts supported on SnO2–Al2O3 exhibit high activity, selectivity towards hydrogen formation, and stability. The effect of Pd on reducibility, surface acidity, and morphology of the Ni supported catalyst, as well as its catalytic properties in OSRM, are discussed in detail.

“…Moreover, the oxidative steam reforming of methanol process (OSRM) is an energetically favored process which can run in the auto-thermal way, without any external heat. Additional advantage of the OSRM is possibility to be carried out at low temperature range 150-330 • C without the carbon deposits formation [3][4][5]. OSRM reaction runs as per the following equation (Equation (1)):…”

“…Based on previous investigations, we decided to prepare bimetallic copper-nickel supported catalysts instead of copper or nickel catalysts promoted by noble elements [21][22][23][24][25]. Copper and nickel catalysts are much cheaper and are characterized by high activity and selectivity in OSRM [5,21,25,26]. Therefore, from the economics point of view, we chose Cu-Ni catalysts supported on binary oxides: ZnO·Al 2 O 3 , CeO 2 ·Al 2 O 3 , ZrO 2 ·Al 2 O 3 .…”

In this work, bimetallic Cu-Ni catalysts supported on binary oxides containing ZnO, ZrO 2 , CeO 2 and Al 2 O 3 were investigated in hydrogen production via the oxidative steam reforming of methanol (OSRM). Their physicochemical properties were extensively studied using various methods such as BET, TPR-H 2 , TPD-NH 3 , XRD, SEM-EDS, ToF-SIMS and XPS. The reactivity measurements showed that the active phase and support composition played an important role in the activity of the catalyst in the OSRM. The most active system at higher temperatures was 30% Cu-10% Ni/CeO 2 ·Al 2 O 3 , with high catalytic activity attributed to the Cu 0.8 Ni 0.2 alloy formation. In addition, the reactivity results showed that the most active catalyst exhibited high acidity and was easily reduced. At low temperatures, the best catalytic properties were exhibited by 30% Cu-10% Ni/ZrO 2 ·Al 2 O 3 . The reactivity and physicochemical properties of the studied catalysts confirmed the crucial role of alloy composition on their catalytic properties in the oxy-steam reforming of methanol. The obtained results validate the possibility of using Cu-Ni catalysts for hydrogen production.

“…That is why from the application point of view oxy-steam reforming process is energetically favourable because it does not require any external heat when it is run. Typical catalysts used in oxy-steam reforming process are monometallic copper [9] or nickel [10] and bimetallic M-Cu copper supported catalysts (where M = Ru, Rh, Pd, Ir) [11][12][13]. Cerium oxide are widely used as an additive to the catalyst support and an essential component of the automotive three-way converter (TWC) [14].…”

The influence of copper content in the monometallic catalysts supported on the CeO 2 ·Al 2 O 3 binary oxide system on their catalytic activity and physicochemical properties in oxy-steam reforming of methanol was investigated. It was shown that activity and selectivity depends on the content of copper, its dispersion on the catalysts surface. It was confirmed that optimal copper content was 20 wt% of Cu. Copper catalysts with 20 wt% of Cu exhibited the highest methanol conversion and reaction rate value compared to the rest of the investigated catalysts systems. The kinetic measurements performed in oxy-steam reforming of methanol on 20%Cu/CeO 2 ·Al 2 O 3 catalysts, showed an activation energy for this system equal Ea (OSRM) = 66.56 kJ/mol.
