Influence of Palladium on Ni-based Catalyst for Hydrogen Production via Thermo-catalytic Methane Decomposition

This study investigates the effect of introducing palladium (Pd) as a promoter on the catalytic performance of Ni/Al2O3 catalysts which were prepared by wet impregnation method at various reaction temperatures. The catalytic activity, thermal stability and deactivation rate of the synthesized cataly...
