Abstract

Inexpensive, and easy to use self cleaning mixtures that use photoactive agents such as titanium dioxide(TiO.sub.2) and tungsten oxide(WO.sub.3) along with mixing the agents with co-catalysts such as carbon(C), Fe(iron), Cu(copper), Ni(nickel) and CO.sub.2 P. In addition, the co-catalyst loading can include up to approximately 5% carbon to maximize the inhibiting algae growth. The mixtures can be used to inhibit various growth organisms such as but not limited to algae, fungus, bacteria and mold. The agents can be combined together, and/or each agent can be combined with various coatings, such as but not limited to a cement or a polymer binder. The coatings can be applied to surfaces that are exposed to water such as but not limited to an aquarium, liners on the inner walls of swimming pools, drinking water tanks, and the like. Additionally, the coatings can be used as surfacing agent in contact with water within solar water heaters, piping adjacent to pool pumps, and the like. Additio
