Hydrogen Production from Steam Reforming of Methanol: Influence of Al-Precursor in Combustion Synthesis of CuO/ZnO/CeO2/Al2O3 Nanocatalyst

Producing hydrogen rich feed via steam methanol reforming was successfully achieved over CuO/ZnO/CeO2/Al2O3nanocatalysts. Various methods used to improve catalytic performance of SRM catalysts. Fuel content plays a key rolein combustion synthesize method as a novel process preparing nanosized mixed oxides. Studying influence of Alprecursor, two CuO/ZnO/CeO2/Al2O3 (45/45/5/10 %wt) catalysts were synthesized via urea nitrate combustionsynthesize method. Once boehmite (AlOOH) used as Al precursor and once Al(NO3)3.9H2O. XRD analysis confirmedthe crystalline phases beside crystalline size reduction and improved dispersion can be seen in EDX dot-mapping analysisin sample with aluminium nitrate precursor. Improved catalytic performance can also be seen for the same sample.
