A coated substrate includes a metallic substrate and a ceramic coating on the metallic substrate. The ceramic coating includes one or more layers, and a total thickness of the ceramic coating is in a range of 2 nm to 200 nm. Coating a metallic substrate includes disposing a first ceramic coating layer on the metallic substrate and disposing one or more additional ceramic coating layers on the first ceramic coating layer to yield a laminated substrate. A total thickness of the ceramic coating layers on the laminated substrate is in a range of 2 nm to 200 nm.

A water-disinfecting apparatus includes a vessel with a cathode, an insert with a photoanode, an ultraviolet light source configured to be positioned in the insert, and a power source. The cathode forms an electrically conductive layer on an inner surface of the vessel. The photoanode is configured to be positioned in the cathode. The power source is configured to be operably coupled to the cathode, the photoanode, and the light source.

Compositions for bromide removal include a two-dimensional material impregnated with silver. The silver may be impregnated in the two-dimensional material by contacting the two-dimensional material with silver ions in an aqueous solution, allowing the silver ions to adsorb on the two-dimensional material, and drying the two-dimensional material. Removing bromide from an aqueous composition including bromide may include contacting the aqueous composition with a two-dimensional material impregnated with silver, and allowing the bromide to react with the silver to yield silver bromide.
