Various techniques examined its structure, composition, and optical properties. This included XRD, XPS, EDS, SEM, TEM, HRTEM, DRS, and PL. The heterojunction showed a reduced charge recombination rate and more excellent stability, helping to lessen photocorrosion. This was due to photogenerated holes moving more quickly out of the CdS valence band. The interface between g-C<sub>3</sub>N<sub>4</sub> and CdS favored a synergistic charge transfer. A suitable flat band potential measurement supported enhanced reactive oxygen species (ROS) generation in degrading 4-nitrophenol and 2-nitrophenol. This resulted in remarkable degradation efficiency of up to 99% andScientific reportsDevelopment of stable S-scheme 2D-2D g-C<sub>3</sub>N<sub>4</sub>/CdS nanoheterojunction arrays for enhanced visible light photomineralisation of nitrophenol priority water pollutants.PMC10844285RSPD2023R865Shah MMahmood SIqbal SBahadur ASaad MAlshalwi MTayyab MfalseDevelopment of stable S-scheme 2D-2D g-C<sub>3</sub>N<sub>4</sub>/CdS nanoheterojunction arrays for enhanced visible light photomineralisation of nitrophenol priority water pollutants.The investigation focused on creating and studying a new 2D-2D S-scheme CdS/g-C<sub>3</sub>N<sub>4</sub> heterojunction photocatalyst.
