%X 采用静电纺丝技术结合水热法构筑碳纳米纤维(CNFs)复合硫化铟(In2S3)异质结构。二维结构的In2S3纳米片被均匀地固载到一维结构的CNFs上，制备的多级结构的CNFs/In2S3复合纳米纤维异质结彼此交错形成开放的三维网络纳米结构。在模拟太阳光的照射下，CNFs/In2S3异质结光催化剂降解抗生素(四环素)在120 min时的去除率达到78.5%。CNFs/In2S3异质结对四环素的移除率约是In2S3粉末的2.02倍，是CNFs的5.27倍。催化剂优异的光催化性能可能与其特殊的异质结构有关，结合光电流数据及阻抗谱分析CNFs/In2S3异质结的构建显著增强了界面电荷的分离和转移效率。
The heterogeneous structure of carbon nanofibers (CNFs) with indium sulfide (In2S3) was constructed by electrospinning combined with a hydrothermal method. Two-dimensional In2S3 nanosheets were uniformly supported on one-dimensional CNFs, and the prepared multilevel CNFs/In2S3 composite nanofiber heterojunctions interleaved with each other to form open three-dimensional network nanostructures. Under the irradiation of simulated sunlight, the removal rate of CNFs/In2S3 heterojunction photocatalyst for degradation of antibiotics (tetracycline) reached 78.5% at 120 min. The removal rate of tetracycline from CNFs/In2S3 heterojunction was 2.02 times that of In2S3 powder and 5.27 times that of CNFs. The excellent photocatalytic performance of the catalyst may be related to its special heterogeneous structure. The construction of CNFs/In2S3 heterojunction combined with photocurrent data and impedance spectrum analysis significantly enhanced the separation and transfer efficiency of interfacial charge.
