In article number 1703484 Jimmy C. Yu and co‐workers report how adding red P nanoparticles onto g‐C 3 N 4 effectively suppresses charge trapping and thus prolongs the lifetime of active charges in the photocatalyst. The optimized red P/g‐C 3 N 4 composite exhibits a very high photocatalytic hydrogen evolution rate of 2565 μmol h −1 g −1 . The charge trapping/de‐trapping processes are thoroughly investigated by time‐resolved transient absorption spectroscopy.
