Carbon nitride in peroxide-coupled photocatalysis for aqueous organic pollutants destruction: Engineered active sites and electron transfer regimes

Efficient photocatalytic degradation of ofloxacin by a polyimide/phosphate-doped porous coralline carbon nitride S-scheme heterojunction

“…13 Simultaneously, the photoexcited conduction band electrons (CB-e − ) can be reduced, yielding superoxide ions (O 2 ˙ − ) and other reactive species (RSs) via electron transfer mechanisms. 14 Within the realm of semiconductor photocatalysts, graphite-phase nitrogen carbide (g-C 3 N 4 , CN) stands out as a cost-effective and readily available metal-free photocatalyst, 15,16 thus finding widespread application in environmental remediation endeavors. However, the practical application of pure CN is constrained by inadequate light utilization, low efficiency in separating photogenerated carriers, and a restricted specific surface area.…”
