Megamerger of MOFs and g-C3N4 for energy and environment applications: upgrading the framework stability and performance

Abstract

Metal–organic frameworks (MOFs) possess large surface area, adjustable pore size and synthetic adaptability which make them promising candidates for diverse applications. However, the low stability and selectivity of pure MOFs are not the optimal configuration for practical applications. Studies have confirmed that the controllable integration of MOFs with graphitic carbon nitride (g-C₃N₄) not only improves the stability and conductivity of pure MOFs, but also unexpectedly yields new functionalities. These advantages allow the synthesized g-C₃N₄/MOF-based materials to be applicable to fields other than pure MOFs and have attracted widespread attention in recent years. Herein, the review aims to specifically group together the important reports focused on g-C₃N₄/MOF-based materials till now. The synthetic methods and applications of composite materials are studied and classified. Furthermore, the review also highlights the functionalities produced by the synergy of two interesting materials, and finally paints a picture of the future.
