1. A filtration membrane, comprising:
a first layer comprising a triamine-functionalized copper oxide polysilicate mesoporous material, wherein the triamine-functionalized copper oxide polysilicate mesoporous material comprises
a copper oxide polysilicate backbone and
a silicon atom of a silicon-containing triamine bonded to a silicate group in the copper oxide polysilicate backbone,
wherein the copper oxide polysilicate backbone is datively bonded to one or more tetramines,
wherein the silicon-containing triamine and the one or more tetramines are covalently cross-linked with terephthaloyl chloride to form a polyamide,
a second layer comprising a polysulfone; and
a third layer comprising a polyester terephthalate.
