Abstract

um tratamento de água catalítico é proporcionado usando um material ativo operado com uma excitação ótica e/ou elétrica. o material ativo é mos2, mose2, ws2, wse2, moxw1-xs2, moxw1-xse2, mosyse2-y, wsyse2-y, ou moxw1-xsyse2-y, onde 0 < x < 1 e 0 < y < 2. o material ativo é configurado como nano estruturas com uma ou mais camadas tendo bordas de camadas expostas. um material catalisador é disposto sobre o material ativo. a estrutura combinada de material ativo e catalisador de metal são dispostos na água a ser tratada. a excitação é proporcionada ao material ativo para gerar uma ou mais espécies de oxigênio reativo pelo dissociação de água, na qual as espécies de oxigênio reativo proporcionam o tratamento de água.
