Abstract

Waste water containing dyes causes serious environmental problems in both aesthetic and toxicological aspects. Although physicochemical and biological treatment processes have been investigated, functional materials are highly demanded for improving the removal efficiency of dye from wastewater To synthesize a heterojunction nanocomposite of CuMn2O4/carbon nanotubes (CNTs) with outstanding catalytic performance for the effective degradation of methylene blue (MB) dye. Copper manganese oxide-carbon nanotubes (CuMn2O4/CNTs) nanocomposite was prepared by a solvothermal method. The structure and morphology of the samples were characterized with X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscopic (TEM), and nitrogen adsorption/desorption on the samples at 77 K. The degradation of methylene blue dye was studied using the prepared nanocomposite as a catalyst. CuMn2O4 of small particles was loaded on CNTs, forming a porous structure with a specific surface area of 43.5 m2/g and a total pore volume of 0.17 cm3/g. The optimum conditions for achieving full breakdown in 10 minutes are 1g/L of catalyst dosage and a range of initial concentrations at 50-100 mg/L of MB dye at pH 4. The synthesized CuMn2O4/CNTs nanocomposite exhibited a good prospect as catalyst materials for the decontamination of wastewater polluted with dyes.

制备碳纳米管支撑的铜锰氧化物纳米复合材料以高效降解亚甲基蓝染料
含有染料的废水在美学和毒理学方面都造成了严重的环境问题。为了有效降解亚甲基蓝(MB)染料,合成了一种催化性能优异的铜锰氧化物/碳纳米管(CNTs)异质结纳米复合材料。 采用溶热法制备了铜锰氧化物-碳纳米管(CuMn2O4/CNTs)纳米复合材料。以制备的纳米复合材料为催化剂,研究了亚甲基蓝染料的降解情况。 小颗粒的 CuMn2O4 被负载在 CNT 上,形成比表面积为 43.5 m2/g、总孔体积为 0.17 cm3/g 的多孔结构。在 pH 值为 4 的条件下,催化剂用量为 1g/L,MB 染料的初始浓度范围为 50-100 mg/L,是在 10 分钟内实现完全分解的最佳条件。 所合成的 CuMn2O4/CNTs 纳米复合材料在染料污染废水的净化过程中作为催化剂材料具有良好的应用前景。
