Recently, semiconducting metal oxide (SMO) gas sensors have attracted the attention of researchers for high conductivity, labile features by environment, low cost, easy preparation, etc. However, traditional SMOs have some defects such as higher operating temperature and lower response value, which greatly limit their application in the field of gas sensor. In this work, the carbon nitride decorated ball-flower like Co3O4 composite was successfully synthesized via a facile hydrothermal method, the composition and morphology of the as-synthesized samples were studied by the techniques of X-ray powder diffraction (XRD), Field-emission scanning electron microscopy (FESEM), Transmission electron microscopy (TEM), Fourier transform infrared spectrometer (FT-IR) and N2-sorption. As a consequence, the pure Co3O4 and the carbon nitride decorated Co3O4 both possess ball-flower like structure, and the as-synthesized carbon nitride decorated Co3O4 composite exhibits significant sensing properties to ethanol which is 1.6 times higher than that of pure Co3O4, furthermore, the composite possesses high selectivity and stability towards ethanol detection.

“…Co., Ltd., Beijing, China). The gas sensor fabrication method and gas sensing test produce were performed as our previously reported method [38]. Response of the gas sensor is defined as follows: Response = R g / R a ( R a and R g are the resistances of the sensor measured in air and in test gas, respectively).…”

The g-C3N4 decorated magnesium ferrite (MgFe2O4) porous microspheres composites were successfully obtained via a one-step solvothermal method. The structure and morphology of the as-prepared MgFe2O4/g-C3N4 composites were characterized by the techniques of X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), thermal gravity and differential scanning calorimeter (TG–DSC) and N2-sorption. The gas sensing properties of the samples were measured and compared with a pure MgFe2O4-based sensor. The maximum response of the sensor based on MgFe2O4/g-C3N4 composites with 10 wt % g-C3N4 content to acetone is improved by about 145 times, while the optimum temperature was lowered by 60 °C. Moreover, the sensing mechanism and the reason for improving gas sensing performance were also discussed.

The nanocomposites of g‐C3N4 nanosheet decorated magnesium ferrite nanoparticles were synthesized by a facile solvothermal method. X‐ray diffraction (XRD), field‐emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM) and thermal gravimetric analysis and differential scanning calorimeter (TG‐DSC) techniques were used to characterize the structure and morphology of the as‐prepared nanocomposites. The results indicated that the MgFe2O4 nanoparticles were highly dispersed on the surface of the g‐C3N4 nanosheet. The gas‐sensing properties of the samples were tested, and the response value (Ra/Rg) of the MgFe2O4/g‐C3N4 nanocomposite with 15 wt.% g‐C3N4 content‐based sensor to 500 ppm of ethanol was 112 at 300 °C, which is 5 times higher than that of pure MgFe2O4. Moreover, the MgFe2O4/g‐C3N4‐15‐based sensor showed impressive selectivity, fast response and recovery characteristics, and good linearity in range of ethanol concentration (10–500 ppm).
