Abstract:

Abstract Based on the ternary complex kinetics model for metallomicelle catalysis, the special dynamic behavior of this kind of super-molecular system related to the capable self-organization formed in it is analyzed in this paper. It is found that a kind of spatial ordered structure in metallomicelle catalytic reaction system can emerge beyond Turing bifurcation if a set of relationships between the characteristic parameters and the externally controlled parameters are satisfied. This self-organization of the concentrations in the metallomicelle system induced by the chemical reaction-diffusion coupling and the non-ideality of the components results in a special spatio-ordered catalytic activity distribution with a maximum. The theoretic results reported in this article will be helpful to explain the ordered catalytic activity characteristic of the metallomicelle system.
