    摘要： A method of making a doped metal oxide includes heating a first doped metal oxide by rapid thermal annealing, to form a second doped metal oxide. The crystal structure of the second doped metal oxide is different from the crystal structure of the first doped metal oxide. The method may provide a doped titanium oxide, where the atomic ratio of dopant nonmetal to titanium is from 2% to 20%, and at least 10% of the doped titanium oxide is in the rutile phase. The method also can provide a doped tin oxide, where the atomic ratio of dopant nonmetal to tin is from 2% to 20%, and at least 50% of 900 the doped tin oxide is in the rutile phase.

    摘要： Composition production methods are provided that can include providing PdO nanoparticles on a nitrogen-doped titanium oxide surface to form a catalytic mixture. Catalytic compositions and/or bactericides are provided that can include a substrate supporting Ti, O, N, and Pd. Water purification methods are provided that can include exposing an aqueous solution to a composition comprising at least a substrate supporting Ti, O, N, and Pd. Photocatalytic methods are provided that can include: providing a composition comprising one or both of Ti and Pd; exposing the composition to visible radiation to activate the composition; and in the substantial absence of the visible radiation, contacting the composition with an aqueous solution to purify the aqueous solution. Embodiments of the disclosure provide visible light photocatalysts that can demonstrate faster photocatalytic disinfection rates on Escherichia coli (E. coli) under visible light illumination as compared to nitrogen-doped titanium oxide (TiON), as well as catalytic activity after visible light illumination is substantially removed.
