The photocatalytic property of the as-synthesized nano- composite was evaluated for the removal of methylene blue (MB). The obtained results showed that the pho- tocatalytic efciency and stability of the composite nanostructures were highly enhanced as compared to the pristine TiO 2 nanofbers. This work demonstrates the efective absorption capacity of carbon nanofber along with the synergistic efect ofMoS 2 and CdS in which it proves to be a good choice for improving the utilization of visible light activity of TiO 2 -based materials. In recent years, semiconductor-based photocatalysis is of growing interest in tackling the global energy and environmental crisis. However, yet, the development of efcient, sustainable, inexpensive, and environmentally-friendly photocatalysts remains a signifcant challenge. Among the semiconductor metal oxides, titanium dioxide (TiO 2 ) has been extensively researched for environmental purifca- tion applications and in water splitting for hydrogen generation [1–4]. Although TiO 2 has a strong oxidation strength and high che- mical stability, due to its wide band gap (3.2 eV) it is only active in the UV light region of the solar spectrum, which accounts less than 5% of the total incident solar light [2,5]. Therefore, for the efective use of TiO 2 , conspicuous eforts have been made to extend its re- sponse spectrum towards the visible spectral region. Diferent stra- tegies such as sensitizing with narrow-band-gap semiconductors or forming new donor states below the conduction band of TiO 2 by the incorporation of metal or non-metal elements into its crystal matrix have been carried out in order to achieve enhanced light harvesting ability under solar irradiation [6–8]. Among the various attempts to enhance the visible light activity of TiO 2 , sensitization of TiO 2 with CdS has been proven to be an excellent strategy for achieving high https://doi.org/10.1016/j.inoche.2019.02.022 Received 10 December 2018; Received in revised form 11 February 2019; Accepted 15 February 2019 ⁎ Corresponding authors.
