catalysis of CO oxidation. Firstly, two shapes, i.e. particulate (P-) and needle-like (N-), CeO2 nanoparticles were formed via … nanoparticles was higher than that of P-CeO2, attributing from the exposed higher-energy {100} and {110} facets for N-CeO2 … nanoparticles. Moreover, the calcined samples with higher degree of crystallinity showed further promotion in catalytic activity. It …
