Traveling interface modulations and anisotropic front propagation in ammonia oxidation over Rh(110)
The bistable NH<sub>3</sub> + O<sub>2</sub> reaction over a Rh(110) surface was explored in the pressure range 10<sup>−6</sup>–10<sup>−3</sup> mbar and in the temperature range 300–900 K using photoemission electron microscopy and low energy electron m...

| Sumario: | The bistable NH<sub>3</sub> + O<sub>2</sub> reaction over a Rh(110) surface was explored in the pressure range 10<sup>−6</sup>–10<sup>−3</sup> mbar and in the temperature range 300–900 K using photoemission electron microscopy and low energy electron microscopy as spatially resolving methods. We observed a history dependent anisotropy in front propagation, traveling interface modulations, transitions with secondary reaction fronts, and stationary island structures. |
