SnS and SnS2 powders were synthesized with the use of ultrasound. The indirect sonication was applied with ultrasound frequency 40 kHz and acoustic power 38 W/L. Products of syntheses were examined with PXRD, TEM, EDX, XPS, and UV–Vis (the Tauc method) investigations. The resulting microparticles were used for tip coating of copper cathodes. These electrodes were used in the degradation of model azo-dye Metanil Yellow by the electro-Fenton process. The efficiencies of degradation using copper, SnS-coated copper, and SnS2-coated copper cathodes are compared. Kinetics of degradation of Metanil Yellow in the electro-Fenton process with the application of three different cathodes is also investigated. It was found that the degradation follows pseudo-first-order and that SnS-coated copper cathode improves the efficiency of degradation, while SnS2-coated copper cathode decreases the efficiency of degradation.

声化学合成的SnS和SnS2在电子Fenton工艺中的应用:动力学和增强的脱色。

利用超声波合成了SnS和SnS 2粉末。间接超声以40 kHz的超声频率和38 W / L的声功率施加。通过PXRD,TEM,EDX,XPS和UV-Vis(Tauc方法)研究检查了合成产物。所得微粒用于铜阴极的尖端涂覆。这些电极用于通过电子芬顿法降解偶氮染料Metanil Yellow。使用铜,SnS涂覆的铜和SnS 2的降解效率比较了涂覆铜的阴极。还研究了在使用三种不同阴极的情况下,电芬顿法中的间苯二酚黄的降解动力学。发现降解遵循伪一级,并且SnS涂覆的铜阴极提高了降解效率,而SnS 2涂覆的铜阴极降低了降解效率。
