Production of hydrogen from methanol over Cu/ZnO and Cu/ZnO/Al2O3 catalysts p…
Abstract. Two series of Cu/ZnO and Cu/ZnO/Al2O3 catalysts with varying Cu/Zn ratio have been prepared by the homogeneous precipitation (hp) method using urea hydrolysis. Steam reforming and oxidative steam reforming of methanol were performed using the hp-Cu/Zn-based catalysts for catalytic production of hydrogen. The hp-Cu/ZnO/Al2O3 catalyst showed a higher activity than the hp-Cu/ZnO catalys…

Preparation of “intelligent” Pt/Ni/Mg(Al)O catalysts starting from commer…
Abstract. Ni/[MgxAl]O (x=3.5, 1.5 and 0.5) doped with trace amounts of Pt were prepared from Mg–Al layered double hydroxides (LDHs) aiming the “green” preparations of “intelligent” reforming catalysts. Commercial Mg–Al LDHs were used as raw materials. The LDHs were calcined and impregnated with Ni(II) and Pt(IV) nitrates at room temperature. The preparative conditions were optim…

Effective MgO surface doping of Cu/Zn/Al oxides as water–gas shift catalysts
Abstract. Trace amounts of MgO were doped on Cu/ZnO/Al2O3 catalysts with the Cu/Zn/Al molar ratio of 45/45/10 and tested for the water–gas shift (WGS) reaction. A mixture of Zn(Cu)–Al hydrotalcite (HT) and Cu/Zn aurichalcite was prepared by co-precipitation (cp) of the metal nitrates and calcined at 300 °C to form the catalyst precursor. When the precursor was dispersed in an aqueous s…

Sustainable Ru-doped Ni catalyst derived from hydrotalcite in propane reform
Abstract. Trace amount of Ru-doped Ni/Mg(Al)O catalyst was prepared from hydrotalcite precursor and was tested in the reforming of propane under daily start-up and shut-down (DSS) operation. Mg(Ni,Al)O periclase derived from the hydrotalcite was dispersed in an aqueous solution of Ru nitrate, followed by calcination and reduction. Finely dispersed Ni–Ru was supported on Mg(Al)O periclase …

Citrate or hydrotalcite? As the precursor of Pt or Ru-doped Ni/Mg(Al)O cataly…
Abstract. Trace amounts of Pt- and Ru-doped Ni/Mg(Al)O catalysts were prepared by a citrate method and tested in the oxidative reforming of C3H8 under daily start-up and shut-down (DSS) operation. The activity and the sustainability of the catalysts were compared with those of the Pt- and Ru-doped Ni/Mg(Al)O catalysts derived from hydrotalcite (HT) precursor. The DSS operation of C3H8 refor…
