Enhanced photocatalytic hydrogen production of MoS(2) sheet/carbon nanofiber using rapid electron transport of Mo(6+) and carbon nanofiber

Normal MoS(2) exhibits a low photocatalytic performance for H(2) production owing to the deficiency of the active sites and the poor electrical conductance. In this work, MoS(2) anchored on the surface of the carbon nanofibers was designed to enhance the activity of the exposed edge and the electric...

description Normal MoS(2) exhibits a low photocatalytic performance for H(2) production owing to the deficiency of the active sites and the poor electrical conductance. In this work, MoS(2) anchored on the surface of the carbon nanofibers was designed to enhance the activity of the exposed edge and the electrical conductivity at the same time. The oxidation of the surface Mo atoms increases the activity of the exposed edge of the MoS(2). The introduction of carbon nanofibers facilitates the effective transportation of the electron–hole pairs by enhancing the electrical conductivity. As a result, the introduction of carbon nanofibers and Mo(6+) can facilitate the electron–hole pair separation to enhance the photocatalytic hydrogen evolution reaction (HER) performance (to eight fold more than normal MoS(2)).
