Graphitic carbon nitride has emerged as a novel visible light responsive photocatalyst in water splitting, carbon dioxide reduction, selective aerobic oxidation, and environmental remediation. Graphitic carbon nitride is synthesized from low-cost earth-abundant materials, it is chemically stable and non-soluble in water, and it shows promising results for photocatalytic oxidation of persistent organic contaminants and microbial inactivation under visible light irradiation, from both a Xenon lamp source and light emitting diodes (LEDs). We are currently working on the development of graphitic carbon nitride with enhanced performance for persistent contaminant removal, pathogen inactivation, and exploring the mechanisms of photocatalytic oxidation.
