|Abstract||Borate and phosphate modified carbon nanotubes with different loading amounts are synthesized by a facile impregnation method and used as metal-free catalyst for oxidative dehydrogenation of isopentane. When the loading of borate was less than 5 wt% B2O3 decrease in isopentane conversion and increase in alkene selectivity was observed, whereas with increase in borate loading exceeding 5 wt% B2O3 the conversion and selectivity remain constant. This phenomenon is significantly different from the volcanic distribution of dehydrogenation selectivity of the phosphate modified carbon nanotubes. We propose that borate modification is more selective than phosphate modification toward the blockage of defects and the inhibition of combustion reaction on the CNTs supported by X-ray photoelectron spectroscopy, temperature-programmed desorption and oxidation. The synergetic effect of borate and phosphate has not been observed in the isopentane oxidative dehydrogenation. (C) 2014 Elsevier B.V. All rights reserved.|
