Catalytic single particle nano-impacts: Theory and experiment. poly(vinylferrocene) modified graphene nanoplatelet mediated L-cysteine oxidation

Abstract:
The theory of catalytic nano-impacts is developed specifically for the case of a single particle in contact with an electrode for a short period of time in which it mediates electron transfer to or from a species in homogeneous solution. The theory is applied to impacts of chemically modified graphene nanoplatelets in which the immobilized ferrocene/ferrocenium couple is used to mediate the oxidation of L-cysteine in aqueous solution. Theory and experiment are in good agreement and the catalytic rate constant is found to be 2.4 ± 1.2 M-1s-1
