摘要：
The effects of Zn-doping on CeO2 nanocrystals were investigated for the catalytic oxidation of carbon monoxide (CO). Incorporating Zn2+ into CeO2 nanocubes with an isotropic 3D structure can effectively regulate oxygen vacancy concentration, compared with CeO2 nanorods showing an anisotropic one dimensional 1D structure. The catalytic activity was shown to be governed by a morphology-dependent doping effect.
