In comparison to Ru catalysts supported on activated carbon (AC), MgO, Al 2 O 3 , and TiO 2 under similar reaction conditions, Ru catalyst using carbon nanotubes as support (Ru/CNTs) was found to show high NH 3 conversion for the generation of CO x -free hydrogen from NH 3 . The modification of the catalyst with KOH leads to a significant improvement...
Magnesia–carbon nanotubes (abbreviated as MgO–CNTs) nanocomposites were prepared by impregnation of CNTs with Mg(NO3)2·6H2O in ethanol solution, followed by drying at 353 K and calcination at 873 K, respectively. The nanocomposites are thermally more stable than CNTs in a H2 flow. The use of the nanocomposites as support yielded more efficient Ru catalysts for the generation of COx-free hydrogen...
