“…Narrow-band gap (NBG) semiconductors are the materials of choice for the catalysis process. These include emerging materials such as metal–organic frameworks (MOFs), CdSe QDs/g-C 3 N 4 , MoO 3 -decorated TiO 2 Z-scheme heterostructures, CdS QDs/g-C 3 N 4 heterostructures and reduced graphene-oxide–Sn 2 S 3 –In 2 S 3 , 49–52 which exhibit superior photocatalytic activity, extended light absorption range, enhanced charge separation efficiency, and improved stability under various reaction conditions. Incorporating these advanced materials into the study expands the understanding of potential alternatives and advancements in wastewater treatment through photocatalytic processes.…”
