英文摘要The development of new materials forever is research front for various application fields, otherwise becomes making bricks without straw. A novel sensing material of rGO decorated W-doped BiVO4 was synthesized for the first time by metal organic decomposition combined with hydrothermal methods for detection of trimethylamine (TEA) vapor. The structure and morphology of material were characterized by spectroscopy techniques. The sensing properties of sensor to TEA were measured. The results showed that the 6WBiVO(4)/rGO5 composite exhibits response of 12.8 and response time of 16 s, which is 5.12 times higher and 2.75 times lower than that of BiVO4, respectively. Moreover, the sensor shows excellent selectivity and stability to 20 ppm TEA at 135 degrees C. The enhancement is ascribed to the increase of electron density, enhancement of specific surface and accelerating of electron transfer for BiVO4 due to W doping, rGO decoration and formation of heterojunctions.
