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…
Abstract. The co-production of hydrogen and carbon nanotubes (CNTs) from the decomposition of ethanol over Fe/ Al2O3 at different temperatures and feeding rates of ethanol was investigated systematically. The results indicated that Fe/Al2O3 was a quite active catalyst for the co-production of hydrogen and CNTs and that its activity and stability depended strongly on the Fe loading. Among al…
