【摘要】 采用简单的水热法制备出不同复合比例的MoS₂/Na₂Fe₂Ti₆O₁₆（MoS₂/NFTO）纳米复合材料,并对复合材料的形貌、化学组分、比表面积、孔径分布及Zeta电位进行表征和分析,研究了所得产物对甲基蓝（MB）染料的吸附性能及吸附动力学.结果表明,相对于纯Na₂Fe₂Ti₆O₁₆,MoS₂质量分数为70%的MoS₂/NFTO复合材料的单位比表面积的吸附容量提高了58倍,对MB的吸附率提高了4.9倍.研究还发现,吸附剂对MB的吸附动力学符合准二级动力学模型.更多还原

【Abstract】 Novel nanocomposites of MoS₂/Na₂Fe₂Ti₆O₁₆（ Mo S2/NFTO） with different ratios were synthesized by a simple hydrothermal method in this paper. The crystal structure,morphology,chemical composition,specific surface area,pore distribution and zeta potential of the composites were analyzed. In addition,we studied the adsorption behaviour and adsorption kinetics of the composites. The results showed that the adsorption capacity per specific surface area of 70%MoS₂/NFTO composite is 58 times higher than that of the pure Na₂Fe₂Ti₆O₁₆,and the adsorption ratio increases 4. 9 times. The adsorption kinetics meets the pseudosecond-order kinetics model.更多还原
