g-C3N4-Based Direct Z-Scheme Photocatalysts for Environmental Applications

Javier Fernandez-Catala et al.

Summary: Photocatalysis is a promising technology for addressing the environmental crisis. One of the most representative photocatalysts is graphitic carbon nitride (g-C3N4), known for its stability, cost-effectiveness, facile synthesis procedure, and absorption properties in visible light. However, the original g-C3N4 still demonstrates low photoactivity due to quick recombination of photo-induced electron-hole pairs. To overcome this limitation, Z-scheme photocatalysts based on g-C3N4 are considered superior alternatives, as they have the same band configuration but a different charge carrier recombination mechanism.
