چکیده
Porous sea urchin-like nickel-doped ZnO with various nickel contents and high specific surface area were synthesized using a solution method followed by calcination. The products consisted of numerous porous nanoleaves. Ni content in these ranged from 5% to 20%. dopants the lattice verified X-ray diffraction photoelectron spectroscopy. sensors based on urchins showed superior sensing performance for some volatile organic compounds (VOCs). 10% doping exhibited best gas-sensing performance, including low working temperature, short response/recovery time, sensor response. In particular, Ni-doped urchin response 84.4 times 17/20 s towards 100 ppm formaldehyde vapor. These behaviors attributed mainly suitable oxygen defects, small nanocrystals, hierarchical structure area.
