Simultaneous production of hydrogen and multi-walled carbon nanotubes by etha…

Abstract. Ethanol decomposition was studied over Ni/Al2O3 catalysts with different Ni loadings (10–90 mol%) at temperatures between 500 and 800 oC to produce hydrogen and multi-walled carbon nanotubes (MWCNTs) at the same time. The hydrogen production increased with increasing temperature and Ni loadings. However, both the quality and the quantity of the nanotubes formed at the relatively…
