Synthesis of a 2D Cu@TiO2 composite via the design of a 1D Cu-based coordination polymer precursor for efficient and selective photodegradation of dyes.


ABSTRACT: A 2D Cu@TiO2 composite with a porous and crystalline structure was successfully synthesized via one-step and low-temperature calcination of a 1D Cu-based coordination polymer (Cu-CP), namely [Cu2(3-dpha)(1,4-NDC)2(H2O)3] n (3-dpha = N,N'-bis(3-pyridyl)adipamide and 1,4-H2NDC = 1,4-naphthalenedicarboxylic acid). Moreover, the Cu@TiO2 membrane was fabricated by a simple filtration of the as-grown Cu@TiO2 composite. Compared with the benchmark TiO2 photocatalyst, the Cu@TiO2 composite material with high specific surface area and reduced photogenerated electron-hole ratio exhibited good photodegradation activity and durability for gentian violet (
