dc.description.abstract | Thin-walled WO3 hemitubes and catalytic Pt-functionalized WO3 hemitubes were synthesized via a polymeric fiber-templating route and used as exhaled breath sensing layers for potential diagnosis of halitosis and diabetes through the detection of H2S and CH3COCH3, respectively. Pt-functionalized WO3 hemitubes with wall thickness of 60 nm exhibited superior acetone sensitivity (R-air/R-gas = 4.11 at 2 ppm) with negligible H2S response, and pristine WO3 hemitubes showed a 4.90-fold sensitivity toward H2S with minimal acetone-sensing characteristics. The detection limit (R-air/R-gas) of the fabricated sensors with Pt-functionalized WO3 hemitubes was 1.31 for acetone of 120 ppb, and pristine WO3 hemitubes showed a gas response of 1.23 at 120 ppb of H2S. Long-term stability tests revealed that the remarkable selectivity has been maintained after aging for 7 months in air. The superior cross-sensitivity and response to H2S and acetone gas offer a potential platform for application in diabetes and halitosis diagnosis. | - |
