Dataset for NiO/ZnO biomorphic nanocomposite using a poplar tree leaf template to generate an enhanced gas sensing platform to detect n-butanol.

The SEM image data presented in this article was collected by the Scanning electron microscopy (SEM) performed on an XL-30 ESEM FEG scanning electron microscopy. The diameter stastics data was collected and calculated by the Image-Pro Plus software system. The UV-Vis Res spectrum was collected by solid state UV diffuse reflector Shimadzu UV-4100 at wavelength 200-800 nm. The SEM image data showed more details of the poplar tree leave template(PTLT). The diameter stastics data show the diameter averagely distributed in the material. The UV-Vis Res spectrum reflected the physical property of PTLT NiO/ZnO. Interpretation of this data can be found in a research article titled "One-step facile synthesis of a NiO/ZnO biomorphic nanocomposite using a poplar tree leaf template to generate an enhanced gas sensing platform to detect n-butanol" (Qingrui Zeng et al., 2019) [1], Research Article DOI: 10.1016/j.jallcom.2019.05.018•The SEM image provide the more details about the distinction of the PTLT ZnO and conventional ZnO, further present more morphology information of the PTLT biotemplate. Exhibiting a facile and green way for synthesising ZnO and narrow down the size of ZnO crystal, present the advantage of PTLT ZnO in morphology control. Motivating gas sensor researcher to fabricate ZnO by a biotemplate method, which owned biomorphic and extraordinary gas sensing properties.•The UV-Vis Res spectrum present more detail of the energy band information of PTLT ZnO and PTLT NiO/ZnO, which is use for the gas sensing mechanism analysis. Inspiring researcher forcus on the construction on p-n heterojunction type gas sensor to enhance the gas sensing properties.•The material researchers work on the morphic investigation, gas sensor, and application of semiconductor.•These data are benefit for the application of biotemplate method for material fabrication and material application.
