Decade Milestone Advancement of Defect-Engineered g-C3N4 for Solar Catalytic Applications

Abstract

Highlights This review summarizes the decade milestone advancement of defect-engineered g-C3N4 and emphasizes the roles of crystallinity and defect traps toward a more precise defective g-C3N4 “customization” in the future. A critical insight into the defect traps has been discussed in depth, probing the defect-induced states and photocarrier transfer kinetics of g-C3N4. The prospect and outlooking for precise defective g-C3N4 “customization” is proposed.
