Hysteresis in catalytic process from the perspective of non-equilibrium thermodynamics
In this paper, the processes of concentrated hysteresis occurring as a result of methane oxidation on platinum nanoparticles are investigated from the perspective of non-equilibrium thermodynamics. It was revealed that the hysteresis is determined by a thermodynamic system transferring under certain conditions from a quasi-stationary state with lower entropy generation to another state with higher entropy generation and in reverse. It is demonstrated that the processes accompanying this hysteresis, similar to the processes of hysteresis in fluid dynamics, heat and mass transfer, aerodynamics, magnetism and other physically diverse systems investigated before, comply with the same validated laws of evolution of non-equilibrium macroscopic thermodynamic systems.
