摘要: A mathematical model is presented which reproduces the experimental results of anisotropic front propagation in bistable H2+O2 reaction on a Rh(110) surface. represented by system two coupled nonlinear reaction–diffusion equations incorporates chemical diffusion adsorbed hydrogen and oxygen. In previous experiments with photoelectron emission microscope (PEEM) it had been demonstrated that H2+O2/Rh(110) anisotropy varied strongly parameters. Depending upon temperature partial pressure fronts were elongated [110]-direction or [001]-direction Rh(110). Key features are oxygen strong inhibitory site-blocking effect adsorption hydrogen. The well data concerning bistability range, dependence velocity pressu...
