摘要：

Catalytic performance of phosphate-modified carbon nanotube（PoCNT） catalysts for oxidative dehydrogenation（ODH） of n-butane has been systematically investigated. The Po CNT catalysts are characterized by SEM, TEM, XPS and TG techniques. We set the products selectivity as a function of butane conversion over various phosphate loading, and it is found that the PoCNT catalyst with the 0.8% phosphate weight loading（0.8PoCNT） exhibits the best catalytic performance. When the phosphate loading is higher than 0.8 wt%, the difference of catalytic activity among the PoCNT catalysts is neglectable. Consequently, the ODH of n-butane over the 0.8PoCNT catalyst is particularly discussed via changing the reaction conditions including reaction temperatures, residence time and n-butane/O2 ratios. The interacting mechanism of phosphate with the oxygen functional groups on the CNT surface is also proposed.
