Rational design of graphene-based sorbents for water purification

Adsorption is an affordable and feasible strategy for water purification. In recent decades, graphene-based adsorbents have emerged as the next-generation sorbents due to their intriguing physicochemical properties like large specific surface area, excellent chemical stability, and two-dimensional structure. In this chapter, recent progresses on the synthesis protocols of graphene-based sorbents are compiled critically. Their environmental applications, especially for the adsorptive removal of dyes from water, are reviewed based on different working mechanisms. At last, current challenges and future prospects are identified.
