Novel Rh(Pd)-Cu(Ni) supported catalysts for oxy-steam reforming of methanol

Abstract The aim of the work was to investigate how the size of Ni and Cu-supported nanoparticles influence their activity in an oxidative steam reforming of methanol. The size of metal particles was controlled by the initial introduction or elimination of oxygen-containing groups on the surface of carbon nanotubes. The results of the activity tests showed that catalysts with the smallest metal nanoparticles were the least active since they easily underwent oxidation during the process.

Herein, we report monometallic Ni and bimetallic Pd–Ni catalysts supported on CeO2–Al2O3 binary oxide which are highly active and selective in oxy-steam reforming of methanol (OSRM). Monometallic and bimetallic supported catalysts were prepared by an impregnation method. The physicochemical properties of the catalytic systems were investigated using a range of methods such as: Brunauer–Emmett–Teller (BET), X-ray Powder Diffraction (XRD), Temperature-programmed reduction (TPR–H2), Temperature-programmed desorption (TPD–NH3), X-ray photoelectron spectroscopy (XPS) and Scanning Electron Microscope equipped with an energy dispersive spectrometer (SEM–EDS). We demonstrate that the addition of palladium facilitates the reduction of nickel catalysts. The activity tests performed for all catalysts confirmed the promotion effect of palladium on the catalytic activity of nickel catalyst and their selectivity towards hydrogen production. Both nickel and bimetallic palladium–nickel supported catalysts showed excellent stability during the reaction. The reported catalytic systems are valuable to make advances in the field of fuel cell technology.
