Publication date: Available online 19 April 2019Source: Materials Research BulletinAuthor(s): Qinyu Zhang, Guanqiong Li, Jie Bai, Ruifang He, Chunping LiAbstractIn this work, we successfully synthesized a series of CdS-BiOCl/PAN composites by two-step method including electrospinning process and hydrothermal process. The CdS-BiOCl/PAN composites showed great photocatalytic performance and chemical stability for H2 production under UV-visible light irradiation due to the synergistic effect among CdS, BiOCl and PAN. Meanwhile, the content of CdS in CdS-BiOCl/PAN composites plays an important role in photo-catalytic abilities. In addition, according to the analysis about the photocatalyst, the possible photocatalytic mechanism and synergistic interaction were further discussed.Graphical abstractThe CdS-BiOCl/PAN composites were successfully fabricated by two-step method including electrospinning process and hydrothermal process. The CdS-BiOCl/PAN composites showed great photocatalytic performance and chemical stability for H2 production under UV-visible light irradiation. The construction of CdS-BiOCl/PAN composites will make a good contribution to design composite catalyst in a wide range of applications.
