“…Therefore, it is urgent to develop high-efficiency treatment technology for antibiotic wastewater purification. Over the past decades, photocatalysis has been considered a promising redox technology for the purification of antibiotic wastewater, 2 which involves two main reaction processes, namely solar light harvesting and the separation of photogenerated electron–hole pairs for the generation of active species (such as singlet oxygen, superoxide radicals, and hydroxyl radicals) toward the decomposition of antibiotics. 3 Clearly, solar light absorption and photocarrier separation are equally important for photocatalysis.…”
