Ethanol steam reforming was studied in the low temperature range (300 – 400ºC) with CexZr1-xO2 (x = 0, 0.5, 0.75 and 1) supported Ni(10wt%) and Rh(1wt%) catalysts. CexZr1-xO2 oxides were prepared by coprecipitation of the corresponding hydroxides using two different cerium salt precursors: ammonium cerium nitrate (ex-A series) and cerium...
