ZnO–SnO 2 composite nanorods with rough surfaces were synthesized via a coaxially nested needle electrospinning method. The morphology and nanostructure were characterized by scanning electron microscopy, atomic force microscope, EDS mapping, nitrogen physical adsorption, and X-ray diffraction. The synthesis mechanisms of ZnO–SnO 2 nanorods were discussed, which combined the gas sensitivity advantages of different materials. ZnO–SnO 2 nanorods sensor with good ethanol gas sensitivity achieved accurate measurement of continuous ethanol concentration. The sensor exhibited good selectivity to ethanol in the presence of formaldehyde, methanol, acetone, acetic acid, benzene, and xylene at 290[Formula: see text]C. The response and recovery time to 100 ppm ethanol were about 13 and 35 s, respectively. The energy band, barrier, charge transfer of ZnO–SnO 2 composite material was discussed, and its optimization of gas sensitivity was analyzed in detail.

Preparation of g-C₃N₄/AgIn(MoO₄)₂ and its photocatalytic degradation of tetracycline hydrochloride

E3S Web of Conferences (2021)

Lijun Jia Qianqian Zhang Xu Yan Ke Zeng

Graphite phased carbon nitride and indium silver molybdate [g-C 3 N 4 / AgIn(MoO 4 ) 2 ]photocatalytic materials were prepared by hydrothermal method. X-ray diffraction, transmission electron microscope, scanning electron microscope, X-ray photoelectric spectrum, UV-vis diffuse reflection spectrum and solid fluorescence were used to analyze its structure and morphology. The results showed that the catalytic activity of g-C 3 N 4 / AgIn(MoO 4 ) 2 was significantly higher than that of pure g-C 3 N 4 and AgIn(MoO 4 ) 2 under visible light irradiation. Under the conditions of g-C 3 N 4 and AgIn(MoO 4 ) 2 with a compound ratio of 2:1 and hydrothermal reaction at 120℃ for 6 hours, the degradation efficiency of tetracycline hydrochloride was the best. After 1 hour of light reaction, the degradation rate of tetracycline hydrochloride could reach 75.3%. g-C 3 N 4 /AgIn(MoO 4 ) 2 is expected to be a promising photocatalyst for wastewater treatment.
