✦ Synopsis

A catalyst was made by entrapping glucose oxidase in a polymeric film deposited on an electrode surface. Its efficiency was studied by measuring the transformation of glucose by oxygen into gluconic acid. A numerical model was elaborated and validated with respect to experimental data. The electrochemical step affected the enzymatic catalysis in two ways: the reactant oxygen was regenerated, and the product, hydrogen peroxide which is a glucose oxidase inhibitor, was consumed. By monitoring these two concentrations, the electrochemical assistance significantly enhanced catalyst efficiency.
