主　　题：Heterostructure Z-scheme Antibacterial Wound healing g-C3N4 

摘      要：The abuse of antibiotics is leading to the emergence of resistant *** this work,a drug-free composite of ZnO/CDots/g-C3N4 with Z-scheme heterojunction was developed,which was employed to kill bacteria effectively within a very short time under the irradiation of visible light due to the enhanced photocatalytic and photothermal *** this system,the CDots acted as a bridge between g-C3N4 and ZnO,effectively inhibiting the recombination of photo-generated electrons with holes and consequently enhancing the photocatalytic *** addition,CDots endowed the system with excellent photothermal *** a result,the antibacterial efficacy of ZnO/CDots/g-C3N4 composite against *** and *** reached up to 99.97%and 99.99%respectively,after 15 min of visible light irradiation,due to the synergistic action of photo-inspired radical oxygen species and *** Zn ions released from the composite promoted the growth of fibroblasts,which accelerated the wound healing process.
