چکیده
|
Mn-doped ceoflower-like microstructures have been synthesized by a facile method,involving the precipitation of metallic alkoxide precursor in a polyol process from the reaction of ceclmiddot;7h with ethylene glycol in the presence of urea followed by calcination. by introducing manganese ions,the composition can be freely manipulated. to investigate whether there was a hybrid synergic effect in chcombustion reaction,further detailed characteristics of mn-doped ceowith various manganese contents were revealed by xrd,raman,ft-ir,sem,eds,xps,osc,htpr,and nadsorption-desorption measurements. the doping manganese is demonstrated to increase the storage of oxygen vacancy for chand enhance the redox capability,which can efficiently convert chto coand h under oxygen-rich condition. the excellent catalytic performance of mco-3 sample,which was obtained with the starting mn/ce ratios of 0.2 in the initial reactant compositions,is associated with the larger surface area and richer surface active oxygen species. © 2015 ling liu et al.
