Hydrogen production by decomposition of methane and methanol mixture over Ni-Pd/Al2O3

Thermocatalytic decomposition of methane (TCD) is a promising method for producing hydrogen. However, the main concerns of this process are very high reaction temperature and fast deactivation of the catalyst. In this work, a positive approach has been made to minimize both effects by using Pd-promo...
