The proposed spray paints consist of heterogeneous nanomaterials with three nanocomponents. Each component is tailored to address a different demand (e.g. high decontaminating efficiency, high contaminant adsorption, and broad solar spectrum utilization), so the resulting paints will exhibit synergic properties by integrating the individual nanocomponents, realizing full potential of latrine coatings in terms of self-decontaminating performance (e.g. durable, affordable, able to be mass produced, easy to clean, and smooth). More specifically, one nanocomponent can absorb visible and infrared lights, another nanocomponent possesses strong adsorption capability to contaminants, bacteria and fungi, and a nanosized ultraviolet photocatalyst serves as the base component. With appropriate chemical modifications, the proposed three-component nanomaterials can be readily incorporated into commercial spray paints as self-decontaminating latrine coatings with enhance cleanliness.
