Moly Disulfide Better at Desalination than Graphene?

IEEE Spectrum reported that molybdenum disulfide may be better at desalinating water than graphene. Scientists have been looking into using graphene in this process, but recently discovered that molybdenum disulfide may be more effective.
As quoted in the market news:

In research published in the journal Nature Communications,  [researchers at the University of Illinois] modeled various thin-film membrane materials and found that MoS₂ was the most efficient, filtering up to 70 percent more water than graphene membranes.
“Finding materials for efficient desalination has been a big issue, and I think this work lays the foundation for next-generation materials,” said Narayana Aluru, a professor at the university and leader of the research, in a press release. “These materials are efficient in terms of energy usage and fouling, which are issues that have plagued desalination technology for a long time.”
