摘　　要：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℃.The good sensing performance may be ascribed to flower-like structure s 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.
