摘要

本文采用简单分散法制备了氧化石墨烯锚定氧化铝掺杂氧化锰纳米颗粒基三元复合材料,用于催化还原水中的有机染料。通过x射线衍射、傅里叶变换红外等表征技术研究了所制备纳米复合材料的结构、形态和热稳定性特征。光谱学,能量色散x射线光谱学和热重量分析。考察了纳米复合材料对亚甲基蓝和甲基橙的催化降解能力。结果表明,三元复合材料对亚甲基蓝的还原具有良好的催化能力,对甲基橙的降解具有显著的效率。此外,还研究了催化剂用量对目标染料还原率的影响。评价的动力学参数,如还原速率常数和R2值,表明制备的纳米复合材料在工业领域的可用性。

Novel graphene oxide@aluminum oxide@manganeseoxide-based ternary nanocomposites: facile synthesis and characterization for catalytic treatment of targeted industrial effluents

Herein, graphene oxide anchored Aluminum Oxide doped Manganese Oxide nanoparticles based ternary nanocomposites were prepared via simple dispersion method to catalytically reduce organic dyes in aqueous media. Structural, morphological, and thermal stability features of the prepared nanocomposite was investigated through various characterization techniques, for example, X-ray Diffraction, Fourier Transform Infrared. Spectroscopy, Energy Dispersive X-ray Spectroscopy and Thermal Gravimetric Analysis. The catalytic potential of the nanocomposite was investigated against catalytic degradation of Methylene Blue, and Methyl Orange. Results indicate that the ternary nanocomposites provide agreeable catalytic capacity towards Methylene Blue reduction, whereas, remarkably efficient towards Methyl Orange degradation. In addition, the effect of catalyst dose on the reduction rate of the targeted dyes was studied. The evaluated kinetic parameters, for example, reduction rate constant and R2 values recommend the usability of the fabricated nanocomposites in industrial domain.
