2D materials engineered membranes for advanced water desalination

This work discloses the role strategic of 2D materials, including
graphene and transition metal dichalcogenides
(TMDs) materials, in membranes designed to water desalination.
Nanocomposite membranes have been realized
to be worked in membrane distillation (MD) and
membrane crystallization (MCr) devices in order to shift
the productivity-efficiency trade-off beyond the state of
the art. Herein, interesting achievements related to higher
production of fresh water and recovery of better-quality
crystals have been discussed, envisaging chemisorption
mechanisms as responsible for enhanced performane of
MD and MCr processes. Comparative analyses have been
done, thereby identifying suitable chemistry-transport relationships
to get competitive membrane operations dedicated
to water desalination. The results discussed have
been achieved within the framework of 2DMEMPUR
project with the financial grant from ‘the Italian Ministry
of Foreign Affairs and International Cooperation’ - Great
Relevance International Project Italy (MAECI)-China
