Abstract
The study of concentration hysteresis in methane oxidation over alumoplatinum catalysts was conducted. It was determined that catalysts activation was accompanied by partial platinum reduction, the boundaries of existence of concentration hysteresis and effect on them of the particle size of the active component were defined.
