Insights into the Active Sites for Catalytic Steam Reforming of Methane from Oscillations in the Reaction

A new oscillating catalytic reaction is discovered: steam reforming of CH<sub>4</sub> in the presence of SO<sub>2</sub> over Rh nanoparticles. The reducing products from the reforming reaction convert SO<sub>2</sub> to adsorbed sulfur, which causes deactivation. W...
