Biomass-engineered graphitic carbon nitride:Structure modulation,charge dynamics,and photocatalytic applicationsOA
Graphitic carbon nitride(g-C_(3)N_(4))is a metal-free,environmentally sustainable semiconductor photocatalyst characterized by its well-defined layered structure,tunable electronic structure,and exceptional optical properties.To address the inherent limitations of g-C_(3)N_(4)that impede its practical application and development,researchers have devised diverse modification strategies,spanning nanostructure engineering,elemental doping/defect introduction,and heterojunction construction.This review underscores the multifaceted synergistic effects derived from the structural diversity of biomass during modification processes.These integrate three core components:(i)Utilizing the unique chiral architecture and abundant functional groups for morphological control.(ii)Band structure engineering through biomass-derived unique skeletons and multielement induced defect formation.(iii)Constructing heterojunctions with unique interfacial effects by integrating biomass materials with different dimensional architectures.Furthermore,synergistic modifications enable atomic-scale lattice engineering with capabilities beyond those achievable by traditional inorganic precursors.Subsequently,we also introduce the applications of biomass-derived modifications in regulating g-C_(3)N_(4)photocatalysts toward addressing energy conversion and environmental remediation challenges.Finally,we delineate the promising trajectory of biomass-engineered g-C_(3)N_(4)photocatalysts,envisioning their expanded deployment in energy conversion systems through synergistic integration with emerging technologies.
