Abstract

“The world is thirsty”, this sentence has spread widely in most scientific events. According to forecasts based on population data reported by the World Bank and FAO’s AQUASTAT database of freshwater availability, it appears that by 2050, 2 billion people living in 44 countries are likely to suffer from water scarcity. Hence, research has focused on developing accurate solutions to provide fresh waters. Currently, the desalination technologies have been presented as an efficient alternative to solve water scarcity. In this perspective, nano porous materials have a lot to offer compared to existing desalination technologies. Herein, the authors provide a mini-review presenting recent advances in the use of graphene in desalination and water purification fields, as well as the various challenges and opportunities to guide future studies in this field.
