TiO₂ grown on MoSe₂ nanosheets was synthesized by a simple process and explored as photocatalyst for hydrogen generation. In visible light, hydrogen generation rate over the MoSe₂/TiO₂ photocatalyst was found to be 468.2 μmol h^− 1 g^− 1, much higher than the corresponding rates obtained over the MoSe₂, TiO₂ and their physical mixture. It is suggested that the good absorption of MoSe₂ to visible light and the improved charge separation by the interface of MoSe₂/TiO₂ greatly promote hydrogen generation rate, as supported by the transient photocurrent responses and electrochemical impedance spectra recorded.

MoSe ₂纳米片上的TiO ₂作为先进的光催化剂，用于在可见光中析氢

通过简单的方法合成了在MoSe ₂纳米片上生长的TiO ₂，并将其作为光催化剂用于制氢。在可见光下，发现在MoSe ₂ / TiO ₂光催化剂上的氢气产生速率为468.2μmolh ^-1  g ^-1，远高于在MoSe ₂ / TiO ₂及其物理混合物上获得的相应速率。这表明MoSe ₂对可见光的良好吸收和通过MoSe ₂ / TiO ₂的界面改善的电荷分离 通过记录的瞬态光电流响应和电化学阻抗谱，大大提高了氢气的产生速率。
