摘要
A preparation method of a two-dimensional nitrogen-doped carbon-based titanium dioxide composite material includes: (1) etching Ti3AlC2 with LiF/HCl to prepare two-dimensional transition metal carbide nanosheet; (2) preparing a nanosheet aggregate by electrostatic self-assembly of a two-dimensional transition metal carbide nanosheet and a positively charged nitrogen-containing cationic compound; (3) calcining the nanosheet aggregates to prepare a two-dimensional nitrogen-doped carbon-based titanium dioxide composite material. A method for degrading and removing organic pollutants in water includes (1) etching Ti3AlC2 with LiF/HCl to prepare two-dimensional transition metal carbide nanosheet; (2) preparing a nanosheet aggregate by electrostatic self-assembly of a two-dimensional transition metal carbide nanosheet and a positively charged nitrogen-containing cationic compound; (3) calcining the nanosheet aggregates to prepare a two-dimensional nitrogen-doped carbon-based titanium dioxide composite material; (4) placing the two-dimensional nitrogen-doped carbon-based titanium dioxide composite material into water containing organic pollutants to degrade and remove organic pollutants in water.
