Low temperature diffusion of Pt atoms from the core to the corners and edges of the Ni cube results in the preparation of potential novel cage-structured Pt catalysts.
The dynamics of lattice oxygen release from perovskite catalysts during NO oxidation was investigated by dispersive X-ray absorption fine structure.
PrMn2O5 is demonstrated as a superior catalyst compared to SmMn2O5 for low temperature NO oxidation, both experimentally and theoretically.
