Oxygen Vacancies Induced Performance Enhancement of Sensitivity to Acetone Using La-Doped ZnSnO₃ Nanosheets: Experimental and DFT-D3 Study

IEEE Sensors Journal, Journal Year: 2023, Volume and Issue: 24(3), P. 2388 - 2395

Published: Dec. 14, 2023

To develop a sensor for acetone gas at low concentrations to protect the environment and human health, La-doped ZnSnO3 (LZSO, La:Sn = 0.25 at%, 0.5 1 at%) nanosheets were prepared by hydrothermal method. The gas-sensing capabilities extensively examined. According results, optimal doping amount is La: Sn at% (LZSO1), LZSO demonstrated best responses of 16.83 427.44 5 100 ppm acetone, respectively, working temperature (325 °C). performance was greatly enhanced compared that nanosheets. concentration oxygen vacancies (VO) improved La doping, which advantageous performance. Furthermore, findings theoretical calculations suggested can increase formation surface vacancies, consistent with results experiments. VO activate surface, reduce work function, promote adsorption, beneficial electron transfer. Thus, method $^{{3}+}$ into promising developing high-performance sensors.
