Gold Nanoparticles Supported on Fe₂O₃–MO(x) (M = Al, Zr, Zn) Composite Oxides for Partial Oxidation of Methanol.

Selective production of hydrogen by partial oxidation of methanol (POM), using gold supported on composite metal oxides, Fe2O3–MO x (M: Al, Zr, Zn) was investigated. The catalysts were characterized by TGA, XRD, TEM and XPS analyses. TGA and DTGA analysis indicates that minimum decomposition temperature required to obtain α-Fe2O3 in Fe2O3–ZrO2 composite support is 570 K.

Hydrogen production by partial oxidation of methanol over gold supported on Fe2O3.

Partial oxidation of methanol (POM) to produce hydrogen was investigated over Au/Fe2O3 catalysts. The catalysts were prepared by inverse co-precipitation method. The influence of catalyst synthesis parameters such as precipitant, gold loading, calcination temperature and reaction parameter such as reaction temperature on POM reaction to produce hydrogen were investigated.
