| description | •Flower-like Zn3Cu2(OH)6(CO3)2 architectures were obtained.•The hierarchically porous CuO/ZnO nanostructures were obtained after calcinations.•The hierarchically porous CuO/ZnO nanostructures exhibit superior gas sensing property.
Porous flower-like CuO/ZnO nanostructures were obtained using a facile chemical solution method combined with subsequent calcination. The calcination of the precursors produced flower-like CuO/ZnO nanostructures, which is comprised of interconnected highly porous CuO/ZnO nanosheets that resulted from the thermal decomposition of the as-prepared precursors, i.e., flower-like zinc copper hydroxide carbonate. Moreover, the nanostructures were characterized through X-ray diffraction, field emission scanning electron microscopy, thermogravimetric–differential thermal analysis, and Brunauer–Emmett–Teller N2 adsorption–desorption analyses, among others. The BET surface area of the hierarchically porous CuO/ZnO nanostructures was calculated at 17.1m2g−1. Furthermore, the gas sensing properties of the as-prepared porous flower-like CuO/ZnO nanostructures were investigated using volatile organic compounds. Compared with the porous flower-like ZnO nanostructures, the porous flower-like CuO/ZnO nanostructures exhibited a higher response and lower working temperature with certain organic vapors, such as ethanol, acetone, and formaldehyde. The responses to 100ppm ethanol and formaldehyde were 25.5 and 28.9, respectively, at a working temperature of 220°C. These results showed that the porous flower-like CuO/ZnO nanostructures are highly promising candidates gas sensing applications. |
