CdS and ZnS co‐sensitised one‐dimensional TiO 2 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/TiO 2 heterojunctions were compared with electrode containing only CdS being superior in terms of photoelectrochemical tests. The results showed that the photocurrent of CdS‐ZnS/TiO 2 nanofibres was seven times than that of CdS/TiO 2 nanofibres and seven times than that of pure TiO 2 nanofibres. The increased photocurrent is depended on the preparation order of ZnS and CdS on TiO 2 nanofibres.
