Microwave assisted synthesis technique was used to prepare palladium supported on iron oxide nanoparticles. The advantage of using microwave irradiation as a synthetic tool is due to its unique features as a one step, simple, versatile, and rapid process. The reactants are added simply at room temperature without using high-temperature injection. Hydrazine hydrate was added by the following ratios (0.1, 0.2, 0.3, 0.4, 0.6, 0.8, 1, 1.6, and 3) ml to the different prepared samples at room temperature in order to investigate its effect on the catalytic performance of the prepared catalysts. The prepared catalyst could be used as an ideal candidate not only for Pharmaceutical industry through cross-coupling reactions but also for low temperature oxidation catalysis of carbon monoxide and pharmaceutical applications as well. The experimental results showed that Pd/Fe3O4 catalyst has a remarkable catalytic activity for carbon monoxide oxidation catalysis due to the strong interaction between palladium and iron oxide nanoparticles. This may be due to the small particle size (7-14 nm) and concentration ratio of the Pd nanoparticles dispersed on the surface of magnetite (Fe3O4). Those nanoparticles were characterized by various spectroscopic techniques including; X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), Vibrating Sample Magnetometer (VSM) and transmission electron microscopy (TEM).

Hierarchical Cu 2 O nanostructures have been successfully fabricated on a large scale using copper acetate and glucose as starting reactants, CTAB as an additive via a microwave-assisted process. The influences of CTAB dosage and reaction time on the morphology of the products were investigated. The resulting Cu 2 O nanostructures were characterized by means of X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM). FESEM images show that the Cu 2 O nanostructures are microsphere, which are composed of nanoparticles. The concentration of CTAB plays a key role in the growth of Cu 2 O nanostructures under experimental conditions. The possible formation mechanism of these hierarchical Cu 2 O nanostructures has been proposed. Meanwhile, the catalytic performances of these Cu 2 O microspheres for thermal decomposition of ammonium perchlorate (AP) were investigated using DSC. The results revealed that Cu 2 O have a great influence on the thermal decomposition of AP. The additions of Cu 2 O powders lower the high decomposition temperature of AP.

In this study, we report on the facile synthesis of a novel electrocatalysts for the oxygen reduction reaction (ORR), based on reduced graphene oxide (RGO), functionalized with metallic and non-metallic elements. In particular, thanks to a fast one-pot microwave-assisted procedure, we induced, in the RGO graphene lattice, a combined doping with nitrogen and sulphur, and the simultaneous decoration with antimony oxide nanocrystals. The multi-doped–decorated material shows enhanced catalytic performance towards ORR, with respect to common nitrogen- or sulphur-doped carbon-based materials. The presence of co-doping is confirmed by transmission electron microscopy and X-ray photoelectron spectroscopy analysis. The detailed electrochemical characterization shows the simultaneous effects of dopant atoms on the catalytic behavior. In particular, the importance of nitrogen and sulphur atoms in driving the oxygen absorption, together with the role of antimony in enhancing the electrochemical performance toward the ORR, are discussed.
