Hierarchical highly ordered SnO2 nanobowl branched ZnO nanowires for ultrasensitive and selective hydrogen sulfide gas sensing

High performance hydrogen sulfide detection is demonstrated for SnO2 nanobowls with branched ZnO nanowires, in-situ fabricated on a MEMS device. Hydrogen sulfide is a particularly hazardous substance to human health, and its detection via MEMS has a number of advantages in practical applications. However, coating the sensing elements directly on to a device is challenging, and often leads to insufficient reliability. Now, a team led by Hong-Liang Lu from F..
