Synthesis of mixed Mn–Ce–Ox one dimensional nanostructures and their catalytic activity for CO oxidation

One dimensional Mn–Ce–Ox composite nanomaterials with various Mn contents were synthesized successfully by a hydrothermal method. The impacts of Mn contents on their morphologies and physical properties were investigated by means of X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS). The analysis reveals that the obtained composites are one-dimensional (1D) rod-like nanostructures. The catalytic behaviors of Mn–Ce–Ox nanomaterials were investigated for CO oxidation. The Mn–Ce–Ox catalysts were found to be more active than catalysts based on ceria alone. The catalytic activities of all one dimensional Mn–Ce–Ox materials for CO conversion are quite high (142
