The combination of CdS and TiO₂nanoparticles led to a red shift (band gap; ca. 2.6 eV) of the absorption band and extended the optical absorption spectrum into the visible region relative to TiO₂。硫化镉的光催化活性/二氧化钛₂-PAN membranes was explored in the degradation of methylene blue dye under visible light irradiation, and the results revealed that the best photocatalytic performance was achieved by 0.1 g CdS/TiO₂-PAN光催化膜与CDS的5％负载/二氧化钛₂hybrid nanoparticles, which degraded 66.29% of methylene blue in 210 minutes at 25°C and pH 8.5. It was found that the optimum loading of nanoparticles in the membranes was 0.1 g. All the photocatalytic membranes showed an insignificant decrease in the photocatalytic activity when used repeatedly. According to literature, CdS/TiO₂-PAN光催化膜之前尚未准备处理模拟废水的目的。SN - 1687-9503 UR - https://doi.org/10.1155/2019/5135618 DO - 10.1155 /五百一十三万五千六百一十八分之二千〇一十九JF - 中华纳米技术的PB - Hindawi出版KW - ER -
