摘要
本文将静电纺丝技术与水热法相结合,成功制备了NiFe_(2)O_(4)/Bi_(2)MoO_(6)复合催化剂。通过X射线衍射(XRD)和傅里叶变换红外光谱(FT-IR),对样品的物相组成进行了分析,利用紫外-可见分光光度计评估了样品的光催化活性。以四环素(TC)为目标污染物,在金卤灯照射的条件下,考察了加入不同浓度的H_(2)O_(2)时该催化剂的光催化性能。结果表明,在金卤灯的照射下,添加0.1mL的H_(2)O_(2)并经20min的光照后,由NiFe_(2)O_(4)/Bi_(2)MoO_(6)催化剂与H_(2)O_(2)构建的光芬顿体系,对四环素的降解效率可达98.6%。
By combining electrospinning technology with the hydrothermal method,NiFe_(2)O_(4)/Bi_(2)MoO_(6)composite catalyst was successfully prepared.The phase composition of the samples was analyzed by X-ray diffraction(XRD)and Fourier transform infrared spectroscopy(FT-IR),and the photocatalytic activity of the samples was evaluated by UV-Vis spectrophotometer.Applied tetracycline(TC)as the target pollutant,the photocatalytic performance of the catalyst was investigated when different concentrations of H_(2)O_(2)were added under the illumination of a metal halide lamp.The results showed that a pure-phase NiFe_(2)O_(4)/Bi_(2)MoO_(6)composite photocatalyst was prepared successfully.Under the illumination of a metal halide lamp,when 0.1mL of H_(2)O_(2)was added and exposed to light for 20min,the degradation efficiency of tetracycline by the photocatalytic system constructed with NiFe_(2)O_(4)/Bi_(2)MoO_(6)catalyst and H_(2)O_(2)was up to 98.6%.
