Well-Separated Photoinduced Charge Carriers on Hydrogen Production Using NiS/TiO Nanocomposites.

Photocatalytic hydrogen production is a sustainable and greenhouse-gas-free method that requires an efficient and abundant photocatalyst, which minimizes energy consumption. Currently, interests in transition metal chalcogenide materials have been utilized in different applications due to their quantum confinement effect and low band gaps. In this study, different wt % of NiS-embedded TiO nanocomposites were synthesized by a facile hydrothermal method and utilized for photocatalytic hydrogen production under extended solar irradiation.

CoS/TiO Nanocomposites for Hydrogen Production under UV Irradiation.

Transition metal chalcogenides have intensively focused on photocatalytic hydrogen production for a decade due to their stronger edge and the quantum confinement effect. This work mainly focuses on synthesis and hydrogen production efficiencies of cobalt disulfide (CoS)-embedded TiO nanocomposites. Materials are synthesized by using a hydrothermal approach and the hydrogen production efficiencies of pristine CoS, TiO nanoparticles and CoS/TiO nanocomposites are compared under UV irradiation.
