The reaction of carbon with hydrogen to form methane in the presence of platinum particles is studied. Kinetics studies are combined with TEM techniques that allow particle shape and structure to be obtained. The methane production has two peaks at 800 and 950 °C. The reaction always involves pitting or channeling by particles moving along the substrate surface. The most active particles are found to be platelets with a (110) surface in contact with the basal plane of the graphite. Those particles have a very rough surface containing many kinks.
