Catalytic activity and reaction rate of the dealloyed Al91.3Ce8Pd0.7 ribbons calcined at 400 °C for CO oxidation with different flow rates at 20 °C (a) and for methane combustion with different flow rates at 320 °C (b) (reaction gas 1 vol% CO/CH4, 10 vol% O2, and 89% vol% N2.). The catalytic activity of the dealloyed Al91.3Ce8Pd0.7 ribbons calcined at 400 °C for CO oxidation in the presence of different O2 concentrations at 80 °C (c) and for methane combustion in the presence of different O2 concentrations at 380 °C (d)
