摘要

Energy shortage and water pollution are two closely related and increasingly serious global issues, among which trace drug pollution in water bodies is receiving increasing attention. Utilizing solar energy for ecological protection and reducing reliance on traditional energy sources has become an urgent issue. We report here a B-doped tubular g-C3N4 with abundant mesoporous architecture prepared based on surface engineering modification technology, which exhibits excellent performance in green hydrogen generation using solar energy and the removal of carbamazepine (as a model pharmaceutical pollutant) from aqueous solution. Under visible light irradiation, the optimized BCN-1 exhibited a hydrogen production rate and carbamazepine degradation rate constant approximately 1.3 and 2.8 times higher, respectively, than tubular g-C3N4.
