Fuel Cell-Grade Hydrogen Production from Methanol Steam Reforming over CuO/ZnO/Al2O3 Nanocatalyst: Effect of Ultrasound Irradiation and Urea/Nitrate Ratio

In this paper, the effects of ultrasound mixing and urea/nitrate ratio on combustion synthesis of CuO/ZnO/Al2O3 nanocatalysts which used for steam methanol reforming process were studied. Due to thispurpose, characteristic analyses such as XRD, FESEM, BET and EDX were used to investigate thephysicochemical properties of prepared nanocatalysts. It was concluded that using ultrasound in mixing step of primary gel preparation can decrease the size of particles and make them more disperse and homogeneous. Furthermore, the best urea/ nitrate ratio for achieving better nano catalysts is 1. These properties lead to better methanol conversion and hydrogen selectivity for CZA-A-CU-UN1
