Highly Sensitive and Selective Detection of Hydrogen Using Pd-Coated SnO<sub>2</sub> Nanorod Arrays for Breath-Analyzer Applications

Highly Sensitive and Selective Detection of Hydrogen Using Pd-Coated SnO<sub>2</sub> Nanorod Arrays for Breath-Analyzer Applications

We report a breath hydrogen analyzer based on Pd-coated SnO<sub>2</sub> nanorods (Pd-SnO<sub>2</sub> NRs) sensor integrated into a miniaturized gas chromatography (GC) column. The device can measure a wide range of hydrogen (1–100 ppm), within 100 s, using a small volume of h...
