The responses of reactants, products and surface intermediates after the steady-state isotopic switch. a, b Normalized mass spectrometry signals of gases in the effluent and c FTIR contour plot collected as a function of time. The feed gas was switched at 0 s from 12CO2/H2/Ar to 13CO2/H2 over 5% Pd/Al2O3 at 533 K. Ar gas was used as an inert tracer
