In this paper, we report synthesis of MoSe2-polyaniline by in-situ polymerization method. Simple and eco-friendly hydrothermal technique is used for the synthesis of MoSe2. Sample characterizations were done using Field Emission Scanning Electron Microscopy (FESEM), X-Ray Diffraction (XRD), UV–vis Spectroscopy, Fourier Transform Infra-Red Spectroscopy (FTIR) and Raman Spectroscopy. Photocatalytic dye degradation was performed using nanocomposite on Methylene blue (MB) and Methyl orange (MO). Photocatalytic degradation efficiency (ƞ) was found to be ∼65% and ∼94% for MB and MO, respectively. Reaction kinetics were studied and fitted well with pseudo first order model because of the mesoporous structure of polyaniline (PANI). Material reusability and regenerability was also checked for number of cycles.

水热合成MoSe 2上苯胺的原位氧化聚合反应增强有机染料的光催化降解
在本文中,我们报道了通过原位聚合法合成MoSe 2-聚苯胺。简单,环保的水热技术用于合成MoSe 2。使用场发射扫描电子显微镜(FESEM),X射线衍射(XRD),紫外可见光谱,傅里叶变换红外光谱(FTIR)和拉曼光谱对样品进行表征。在亚甲基蓝(MB)和甲基橙(MO)上使用纳米复合材料进行光催化染料降解。发现MB和MO的光催化降解效率(ƞ)分别为〜65%和〜94%。由于聚苯胺(PANI)的介孔结构,研究了反应动力学并很好地拟合了拟一阶模型。还检查了材料的可重复使用性和可再生性的循环次数。
