Summary: The ZnSnO3 hollow cubes were successfully modified by Ag nanoparticles, which generated Schottky barrier-type junctions and enhanced the sensing performance. The gas-sensing results showed excellent response value (26.7) towards 50 ppm formaldehyde at 100 degrees C, as well as fast response/recovery time (12/18 s), remarkable reproducibility, and outstanding stability. The sensing mechanism was proposed based on the structure of ZnSnO3 hollow cubes and the catalytic activity of Ag NPs. This work confirms that Ag NPs modification is an efficient strategy to improve the sensing properties of ZnSnO3-based gas sensors.
