Enhanced H2S gas sensing performance of networked CuO-ZnO composite nanoparticle sensor
Source abstract
Abstract
Abstract CuO-ZnO composite nanoparticles (CuO:ZnO = 4:1 by vol.%) were synthesized via a facile solvothermal route. The CuO-ZnO composite nanoparticle sensor showed significantly enhanced H 2 S gas sensing performance compared to the pristine CuO and pristine ZnO nanoparticle sensors. The pristine CuO, pristine ZnO and CuO-ZnO composite nanoparticle sensors showed responses of approximately 335%, 161% and 1035%, respectively, to 2 ppm of H 2 S at 225 °C. The CuO-ZnO composite nanoparticle sensor also showed more rapid response to H 2 S gas than the pristine CuO and ZnO nanoparticle sensors. Both the pristine CuO nanoparticle and CuO-ZnO composite nanoparticle sensors showed selectivity for H 2 S gas over other gases. The underlying mechanism for the enhanced sensing performance of the CuO-ZnO composite nanoparticle sensor is discussed.
