Abstract The thermal stability of Au nanoparticles on ceria support of various morphology (nanocubes, nanooctahedra, and {111}-nanofacetted nanocubes) in oxidizing and reducing atmospheres was investigated by electron microscopy. A beneficial effect of the reconstruction of edges of ceria nanocubes into zigzagged {111}-nanofacetted structures on the inhibition of sintering of Au nanoparticles was shown. The influence of different morphology of Au particles on various ceria supports on the reducibility and catalytic activity in CO oxidation, and CO PROX of Au/ceria catalysts was also investigated and discussed. It was shown, that ceria nanocubes with flat {110} terminated edges are more suitable as a support for Au nanoparticles, used to catalyze CO oxidation, than zigzagged {111}- nanofacetted structures.

AbstractIt is a novel approach to the synthesize Poly(aniline) / V2O5 nano composite by free radical polymerization method under different experimental conditions such as variation in time, temperature and concentration of aniline and initiator. It was indicated that V2O5 itself could catalyze the oxidative polymerization of aniline. This can be attributed to the internal doping effect, which introduced flexibility to the rigid PANI backbone. TGA counseled the thermal stability of PANI. Through FTIR study, the structure of PANI was established. Comparison of polymerized aniline composite with two different initiators was done.
