Molybdenum disulfide and related materials for water treatment
Abstract
Catalytic water treatment is provided using an active material driven with an optical and/or electrical excitation. The active material is MoS2, MoSe2, WS2, WSe2, MoxW1-xS2, MoxW1-xSe2, MoSySe2-y, WSySe2-y, or MoxW1-xSySe2-y; wherein 0 < x < 1 and 0 < y < 2. The active material is configured as one or more layered nanostructures having exposed layer edges. A metal catalyst is disposed on the active material. The combined structure of active material and metal catalyst is disposed in the water to be treated. The excitation is provided to the active material to generate one or more reactive oxygen species by dissociation of water, wherein the reactive oxygen species provide water treatment.
