text: Clean hydrogen is a key aspect of carbon neutrality, necessitating robust
methods for monitoring hydrogen concentration in critical infrastructures like
pipelines or power plants. While semiconducting metal oxides such as In2O3 can
monitor gas concentrations down to the ppm range, they often exhibit cross-sensitivity
to other gases like H2O. In this study, we investigated whether cyclic optical
illumination of a gas-sensitive In2O3 layer creates identifiable changes in a
gas sensor´s electronic resistance that can be linked to H2 and H2O concentrations
via machine learning. We exposed nanostructured In2O3 with a large surface area
of 95 m2 g-1 to H2 concentrations (0-800 ppm) and relative humidity (0-70%) under
cyclic activation utilizing blue light. The sensors were tested for 20 classes
of gas combinations. A support vector machine achieved classification rates up
to 92.0%, with reliable reproducibility (88.2 ± 2.7%) across five individual sensors
using 10-fold cross-validation. Our findings suggest that cyclic optical activation
can be used as a tool to classify H2 and H2O concentrations.
