Abstract

AbstractCompared with conventional metal‐based catalysts, carbon nanotubes (CNTs) exhibit advantages of tunable surface chemical composition and structure. The complicated synthetic technique of traditional methods limited large‐scale production of CNTs. Carbon nanotube (CNT−R) was successfully prepared by simple carbonization of the industrial anion resin with cyanocobaltate. The CNT−R was characterized by X‐ray diffraction (XRD), N2 physisorption, scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Characterization indicates that the CNT−R shows hierarchically porous structure, large pore volume and highly graphitization. The catalyst shows high catalytic activity in the oxidative dehydrogenation of ethylbenzene to styrene.
