摘要：

为了解决氧化石墨烯（GO）膜不稳定性和低水通量的问题，本文利用水热法制备了二硫化钼（MoS2）纳米片与还原氧化石墨烯（RGO），并通过真空抽滤法在聚醚砜支撑膜上制备出MoS2/RGO复合膜。结果表明，当MoS2与RGO的质量比为9：10时，所制备的复合膜表现出高达35 L/(m2·h·MPa)的水渗透率，为纯氧化石墨烯膜的10.6倍，对硫酸钠的截留率达到86.7%，并且对甲基蓝以及刚果红的截留率分别为97.8%、98.6%，同时，对不同pH和不同浓度刚果红溶液的截留率均达到95%以上。此外，经测试该膜具有较好的稳定性，在水处理分离复合膜中具有巨大的应用潜力。

In order to solve the problems of instability and low water flux of graphene oxide (GO) membranes, molybdenum disulfide (MoS2) nanosheets with reduced graphene oxide (RGO) were prepared by hydrothermal method in this paper, and MoS2/RGO composite membranes were prepared on polyethersulfone supported membranes by vacuum filtration. The results showed that when the mass ratio of MoS2 to RGO was 9:10, the prepared composite membranes exhibited a pure water flux of up to 35 L/(m2·h·MPa), which was 10.6 times higher than that of pure graphene oxide membranes, and achieved a retention rate of 86.7% for sodium sulfate, and 97.8% and 98.6% for methyl blue and Congo red, respectively, while the retention rates of different pH values, different The retention rate of Congo red at different pH values and concentrations reached over 95%. In addition, the membrane has been tested to have good stability and has great potential for application in water treatment composite membranes.
