Catalytic CH$_4$ Oxidation Light-off Movies of Pd/Al$_2$O$_3$ and Pd/CeO$_2$ Model Catalysts

Movies of the HEGIXRD and MS data of Pd/Al$_2$O$_3$ and Pd/CeO$_2$ model catalysts recorded during CH$_4$ light-off at the ID31 beamline of the ESRF. The temperature range of the light-off experiments is 411K to 827 K with a ramp of ~5 K/min, the reactor pressure is 100mbar, the total flow 100ml/min with a composition of 20% O$_2$, 0.1% CH$_4$, and 79.9% Ar.
