Carbon nanotibers (CNFs) have been immobilized onto carbon felt as the first step for their industrial application in oxidative dehydrogenation (ODH) reactions, exhibiting stable performance with a high selectivity to styrene in the ODH of ethyl benzene at temperatures around 300 K lower than that of the actual industrial process, and inhibiting Problems of loose small particles when CNFs are used as catalyst in fixed-bed reactors.
