Abstract

This investigation looks at the way sulfur-doped graphitic carbon nitride (S-g-C₃N₄) and vanadium-doped iron molybdate (V-MoFe₂O₄) nanocomposites are prepared and tested for their effect on environmental protection. To produce S-g-C₃N₄, a solvothermal method was used and V-MoFe₂O₄ nanoparticles were made using a hydrothermal approach by doping vanadium at differing amounts (2, 4, 6, 8 and 10 mol%). The methylene blue (MB) dye was tested under sunlight to evaluate photocatalytic activity. V-MoFe₂O₄ with an 8 mol% amount of V achieved the maximum degradation efficiency in all the samples. Nanocomposites with certain contents of S-g-C₃N₄ (including 10 %, 50 %, 70 % and 90 %) and 8 % of V-MoFe₂O₄ formulations were made to increase activity. The S-g-C₃N₄/V-MoFe₂O₄ composite (90 % S-g-C₃N₄ + 8 % V-MoFe₂O₄) did the best job of removing dyes in a little over two hours. Through X-ray diffraction (XRD), FTIR, scanning electron microscopy (SEM) and UV–visible spectroscopy, we showed that the nanocomposites formed correctly and had good structural features. According to these findings, the S-g-C₃N₄/V-MoFe₂O₄ combination could be a good choice for treating wastewater using solar power.

掺钒钼铁氧体NPs/S-g-C3N4光催化降解染料复合材料的制备及应用

本文研究了硫掺杂石墨氮化碳（S-g-C3N4）和钒掺杂钼酸铁（V-MoFe2O4）纳米复合材料的制备方法，并对其环保效果进行了测试。为了制备S-g-C3N4，采用溶剂热法制备了V-MoFe2O4纳米颗粒，并通过水热法制备了不同量（2、4、6、8和10 mol%）的钒。对亚甲基蓝（MB）染料在日光下的光催化活性进行了测试。当V含量为8mol %时，V- mofe2o4在所有样品中的降解效率最高。制备了S-g-C3N4（10%、50%、70%和90%）和V-MoFe2O4（8%）含量的纳米复合材料，以提高活性。S-g-C3N4/V-MoFe2O4复合材料（90% S-g-C3N4 + 8% V-MoFe2O4）在2小时多一点的时间内脱除染料效果最好。通过x射线衍射（XRD）、红外光谱（FTIR）、扫描电镜（SEM）和紫外可见光谱（UV-visible spectroscopy）等分析表明，所制备的纳米复合材料成形正确，具有良好的结构特征。根据这些发现，S-g-C3N4/V-MoFe2O4组合可能是利用太阳能处理废水的良好选择。

期刊介绍： Polyhedron publishes original, fundamental, experimental and theoretical work of the highest quality in all the major areas of inorganic chemistry. This includes synthetic chemistry, coordination chemistry, organometallic chemistry, bioinorganic chemistry, and solid-state and materials chemistry. Papers should be significant pieces of work, and all new compounds must be appropriately characterized. The inclusion of single-crystal X-ray structural data is strongly encouraged, but papers reporting only the X-ray structure determination of a single compound will usually not be considered. Papers on solid-state or materials chemistry will be expected to have a significant molecular chemistry component (such as the synthesis and characterization of the molecular precursors and/or a systematic study of the use of different precursors or reaction conditions) or demonstrate a cutting-edge application (for example inorganic materials for energy applications). Papers dealing only with stability constants are not considered.
