Bilayer sensors and sensor arrays with a catalytic CeO2 filter are proposed as a facile platform for high-performance gas sensors and electronic noses. Authors show the bilayer sensors enhance selectivity toward aromatic compounds, and the arrays provide comprehensive information such as gas concentration and composition.
