Synthesis and characterization of manganese doped CeO2 nanopowders from hydrolysis and oxidation of Ce37Mn18C4s
The Mn-doped Ce02 nanopowders with high catalysis activity were successfully fabricated through a simple hydrolyzed-oxidized approach. Firstly, the alloy Ce37Mnl 8C45 was prepared in vacuum induction melting furnace. Subsequently, Mn-doped CeO2 nanopowders with 142 m2/g of specific surface area were...

| description | The Mn-doped Ce02 nanopowders with high catalysis activity were successfully fabricated through a simple hydrolyzed-oxidized approach. Firstly, the alloy Ce37Mnl 8C45 was prepared in vacuum induction melting furnace. Subsequently, Mn-doped CeO2 nanopowders with 142 m2/g of specific surface area were obtained through a simple hydrolyzed-oxidized procedure of the alloy Those nanopowders were heat treated at different temperatures. The obtained materials were characterized by X-ray diffraction （XRD）, transmission electron microscopy （TEM）, high-resolution transmission electron microscopy （HRTEM） and energy dispersive spectroscopy （EDS）. And the catalytic activity on vinyl chloride （VC） emission combustion was investigated. The results showed that those nanopowders after hydrolyzed-oxidized from Ce37Mn18C45 mainly consisted of CeO2 and Mn304. Manganese element increased the thermal stability of CeO2 nanopowders. The Mn-doped CeO2 nanopowders had three morphologies. Small particles were Mn-doped CeO2, square particles were Mn304 and the rods were Mn304 and Mn203. The Mn-doped CeO2 nanopowders had good vinyl chloride （VC） emission catalytic performance. |
