Compact thermolysis of zinc acetate dihydrate in a sealed bath reactor at 400 degrees C over 20 h yielded the nanoforest structures. A carbon shell layer coating was applied in situ during the growth of the ZnO nanosheet core. The structures, morphologies, growth processes, compositions, and binding characteristics of the ZnO/C core-shell HNS nanoforests were analyzed using multi-purpose high-performance X-ray diffraction (XRD), scanning electron microscopy, energy-dispersive X-ray spectroscopy, Raman spectroscopy, transmission electron microscopy, and X-ray photoelectron spectroscopy (XPS) techniques. XRD and XPS results suggest the existence of oxygen vacancy defects in the core surface of ZnO/C core-shell. The ZnO/C core-shell HNS nanoforests exhibited strong absorption features from the visible to the near-IR region (400-1670 nm), and the nanoforest films showed high electrical conductivity.
