Abstract The functionalized fabrics were fabricated using diethyl zinc and deionized water as precursors to deposit ZnO onto self-supporting carbon nanotube (CNT) fabrics by atomic layer deposition(ALD). The microstructure morphologies, crystal structure, surface properties and photocatalytic activities of the fabrics were investigated during ALD. ZnO grows on the CNTs surface as nanoparticulates initially and then forms conformal layers wrapping the CNTs with rising ALD cycles. The oxide loadings in CNT fabrics can be precisely regulated by changing ALD deposition conditions. The originally hydrophobic surface of fabrics is progressively turned to be highly hydrophilic. The combination of CNTs and hexagonal wurtzite ZnO could effectively enhance the electron transfer ability and significantly reduce the recombination probability of photo-generated electrons and holes. The ALD-modified CNT fabric exhibits excellent photocatalytic degradation performance, demonstrating that ALD is an efficient and flexible method for the functional modification of CNT fabrics.
