▎ 摘　　要

NOVELTY - Desalinating seawater using porous graphene comprises pre-processing the sea water, repeatedly filtering to obtain sea water desalination, and (ii) desalting desalination of seawater with graphene sieve body layer, collecting to obtain drinkable fresh water, where the graphene mesh layer is a porous graphene with a hole size of 1 nano and has a sloping roof structure, The sea water which can be used for desalination passes porous graphene with a sloping roof structure to complete desalination and desalination. USE - The method is useful for desalinating seawater using porous graphene (claimed). ADVANTAGE - The method saves more energy.
