Photoelectrochemical water oxidation over TiO(2) nanotubes modified with MoS(2) and g-C(3)N(4)

TiO(2) nanotube arrays (TNAs) have been studied for photoelectrochemical (PEC) water splitting. However, there are two major barriers of TNAs, including a low photo-response and the fast charge carrier recombination in TNAs, leading to poor photocatalytic efficiency. Through a comparison of MoS(2)/T...

description TiO(2) nanotube arrays (TNAs) have been studied for photoelectrochemical (PEC) water splitting. However, there are two major barriers of TNAs, including a low photo-response and the fast charge carrier recombination in TNAs, leading to poor photocatalytic efficiency. Through a comparison of MoS(2)/TNAs and g-C(3)N(4)/TNAs, it was found that TNAs modified with MoS(2) and g-C(3)N(4) exhibited a current density of, respectively, 210.6 and 139.6 μA·cm(−2) at an overpotential of 1.23 V vs RHE, which is 18.2 and 12 times higher than that of pure TNAs under the same conditions. The stability of the MoS(2)/TNAs heterojunction is higher than that of g-C(3)N(4)/TNAs.
