Exhaustive mapping of Co-Mo catalytic activity against their compositions in growing SWNTs from ethanol

Abstract

In the direct growth of SWNTs on substrates by CVD methods, preparation of the catalyst nanoparticles is a crucial issue. Co-Mo binary catalysts effectively grow SWNTs either from CO [1] and from alcohol [2]. However, different values are reported as the optimum Co/Mo atomic ratio; 1/3 for the former [1] and 1/1 for the latter [2]. The structure of catalyst… (More)
