Abstract

Membrane separation processes have been considered as general techniques for separation and purification of water, for they guarantee a number of worldwide advantages in terms of their economics and outstanding practical selectivity. However, fouling restricts the efficiency of membranes, necessitating modification of their bulk and surface characteristics. Incorporation of nanomaterials into the membrane matrix has been intended as a prominent strategy, where carbon-based nanostructures played a key role in diminishing fouling. Graphitic carbon nitride (g-C3N4) composed of carbon and nitrogen has attracted significant attentions in membrane fabrication owing to its hydrophilic nature, acceptable thermal stability and photocatalytic property. In this review, a brief explanation of the history of g-C3N4 was provided, followed by classification and explanation of different ways attempted in fabrication of g-C3N4 membranes. In addition, the influence of g-C3N4 on the efficiency of membrane processes was comprehensively discussed. Finally, the challenging aspects of the future usage of g-C3N4 in industrial scale processes were discussed. (c) 2021 Institution of Chemical Engineers. Published by Elsevier B.V. All rights reserved.
