Abstract
CdS and ZnS co-sensitised one-dimensional TiO2 nanofibres were successfully prepared by a combination of electrospinning and successive ionic layer adsorption and reaction (SILAR) process because both electrospinning and SILAR method are inexpensive and scalable techniques. The composites of CdS-ZnS/TiO2 heterojunctions were compared with electrode containing only CdS being superior in terms of photoelectrochemical tests. The results showed that the photocurrent of CdS-ZnS/TiO2 nanofibres was seven times than that of CdS/TiO2 nanofibres and seven times than that of pure TiO2 nanofibres. The increased photocurrent is depended on the preparation order of ZnS and CdS on TiO2 nanofibres.
