Ni(II)-Mg(II)-Al(III) catalysts for hydrogen production from ethanol steam reforming: Influence of the Mg content
The Ni(II)Mg(II)Al(III) LDH were obtained by homogeneous precipitation urea method, after a proper thermal treatment resulted in an active catalyst for the ethanol steam reforming. After catalytic performance, catalysts were analyzed by temperature programmed oxidation (TPO), in order to quantify ca...
