Novel TiO₂/GO-Al₂O₃ Hollow Fiber Nanofiltration Membrane for Desalination and Lignin Recovery.

ABSTRACT: Due to its greater physical-chemical stability, ceramic nanofiltration (NF) membranes were used in a number of industrial applications. In this study, a novel NF membrane was prepared by co-depositing a titanium dioxide (TiO₂) and graphene oxide (GO) composite layer directly onto a porous α-Al₂O₃ hollow fiber (HF) support. An 8 µm-thick TiO₂/GO layer was deposited to the surface of α-Al2O3 HF support by vacuum deposition method to produce advanced TiO₂/GO-Al₂O₃ HF NF membrane.
