Cerium fluoride (CeF3) semiconductor with upconversion property was constructed on graphite car-bonitride (g-C3N4) nanosheets by microwave hydrothermal method.The X-ray diffraction,transmission election microscopy,Fourier transform infrared,and X-ray photoelectron spectra techniques were used to characterize the CeF3/g-C3N4 nanocomposite.The study shows that CeF3 has upconversion property and can convert visible light (Vis) and near-infrared light (NIR) into ultraviolet light (UV).Moreover,CeF3 and g-C3N4 can form well-defined heterojunction and promote the effective separation of photo-generated electrons and holes.The synergistic effect of the CeF3/g-C3N4 nanocomposite was evaluated by photocatalytic degradation of dibenzothiophene (DBT).The optimum photocatalyst of CeF3/g-C3N4(40 wt％) composites exhibit the highest photocatalytic desulfurization rate of the model oil under visible light radiation.

爆破片广泛应用于石油、化工、航空航天领域,在压力容器及管路安全保护方面具有重要的作用。反拱带槽型爆破片依靠结构失稳破坏打开,其失稳压力即为打开压力。在选定材料及直径的情况下,爆破片打开压力主要与其厚度、起拱高度、减弱槽剩余厚度等结构参数相关。为了提升反拱带“十字”槽型爆破片成型工艺性能,本文研究了爆破片的主要结构参数对打开压力的影响规律,分析了参数选取对成型工艺及性能的影响,给出了参数选取的基本原则,对于爆破片的工程应用具有一定的指导作用。
