The disclosure is directed to a surface having a binding component applied thereto for the adsorption or capture of pathogens and organic molecules or materials. The surface may be a component of a porous or nonporous substrate. The binding component may also bind a photocatalyst to the surface for photocatalytic destruction of the captured pathogens and organic molecules or materials.

Functionalized surfaces for the destruction of pathogens and organics

Substitution of a single Ga-atom or single Ge-atom (GaAland GeAlrespectively) into the center of an aluminum Keggin polycation (Al) produces an optimal water-treatment product for neutralization and coagulation of anionic contaminants in water. GaAlconsistently shows &#x2dc;1 order of magnitude increase in pathogen reduction, compared to Al. At a concentration of 2 ppm, GaAlperforms equivalently to 40 ppm alum, removing &#x2dc;90% of the dissolved organic material. The substituted GaAlproduct also offers extended shelf-life and consistent performance. We also synthesized a related polyaluminum chloride compound made of pre-hydrolyzed dissolved alumina clusters of [GaOAl(OH)(HO)].
