Preparation of the polymerized surfactant vesicle matrix and the colloidal platinum catalyst within this matrix is described. Colloidal formation and polymerization were monitored by absorption spectroscopy. The catalytic efficiency of vesicle entrapped colloidal platinum was demonstrated. Bubbling of hydrogen through a solution containing this vesicle resulted in the reduction of methylene blue and 10-methyl-5-deazaisoalloxazine-3-propanesulfonic acid. No reduction occurred in the absence of the colloidal platinum either in vesicles or in homogeneous solutions. The reduced polymer matrix can be reoxidized by the addition of ferric chloride. The feasibility of the use of these systems was demonstrated satisfactorily. 3 figures.
