In-situ growth of V2O5 flower-like structures on ceramic tubes and their trimethylamine sensing properties

V2O5 flower-like structures assembled by thin nanosheets were in situ growth on ceramic tubes by hydrothermal process. The structural characterization indicates that V2O5 flower-like structures is orthogonal diamond phase, which entirely covered on the surface of ceramic tubes. TMA sensing measured results revealed that the sensor based on V2O5 flower-like structures exhibited fast reversible and response, good selectivity to TMA and good stability at 200 degrees C. The good sensing performance may be ascribed to flower-like structures and directly growth sensing film on the ceramic tube without structure damage. Our works give a simple in situ growth flower-like structures route on sensing device, which exhibits potential application for detecting trace amounts of TMA gas.
