This article is published with open access at Abstract In this article direct coating of ZnO on PEC-VD-grown multi-walled carbon nanotubes MWCNTs is achieved using atomic layer deposition ALD . Transmission electron microscopy investigation shows that the deposited ZnO shell is continuous and uniform in contrast to the previously reported particle morphology. The ZnO layer has a good crystalline quality as indicated by Raman and photoluminescence PL measurements. We also show that such ZnO layer can be used as seed layer for subsequent hydrothermal growth of ZnO nanorods resulting in branched CNT-inorganic hybrid nanostructures. Potentially this method can also apply to the fabrication of ZnO-based hybrid nanostructures on other carbon nanomaterials. Keywords ZnO Atomic layer deposition Carbon nanotubes Hybrid nanomaterials Hydrothermal Solar cells Introduction Carbon nanotube CNT and inorganic composite materials have attracted much attention recently due to their potential application such as in photocatalyst gas sensors supercapacitors and field emission devices 1 .
