摘要Two coordination polymers (CPs), [Cd-3(L)(3)(phen)(2)](n) (1) and [Mn(L)(phen)](n) (2), [H3L=3,3 '-(1,4-phenylenebis(methylenoxy)dibezoic acid] were synthesized via hydrothermal method. 1 features a 2D layered structure with the potential for 3D network formation through weak interactions, 2 exhibits a 1D waved chain capable of forming 3D polymeric chains via intra- or intermolecular hydrogen bonding (OH center dot center dot center dot O) interactions. Both CPs demonstrate promising photocatalytic activity against antibiotics, including chloramphenicol (CAP), metronidazole (MDZ), nitrofurazone (NFZ), oxytetracycline (OXY), and sulfamethazine (SMZ). Notably, CP 1 shows superior photocatalytic activity for NFZ degradation. Systematic investigations revealed that under optimized conditions, CP 1 achieves a remarkable similar to 92.21 % photodegradation of NFZ at a concentration of 40 ppm NFZ with a photocatalyst dosage of 25 mg/L within 50 min. Radical quencher experiments identified h(+) (positive holes) and O-2(center dot-) as the primary active species driving the photodegradation process. Additionally, CP 1 maintained consistent performance over five cycles, indicating its stability and reusability for NFZ degradation.
