A novel 3 D mesoporous black TiO2 (MBT)/MoS2/MBT sandwich‐like nanosheet was successfully fabricated using a facile mechanochemical process combined with an in situ solid‐state chemical reduction approach, followed by mild calcination (350 °C) under an argon atmosphere. The MBT/MoS2/MBT exhibits a 3 D sandwich‐like nanosheet structure and heterojunctions are formed at the interfaces between MoS2 and black TiO2. The significantly narrowed band gap of MBT/MoS2/MBT is attributed to the introduction of MoS2 and the formed Ti3+ species in the frameworks. The visible‐light photocatalytic degradation rate of methyl orange and the hydrogen production rate are as high as 89.86 % and 0.56 mmol h−1 g−1, respectively. The introduction of MoS2 and Ti3+ in the frameworks favors the visible‐light absorption and the separation of photogenerated charges, and the 3 D sandwich‐like heterojunction structure facilitates the transfer of photogenerated charges.

制备3D介孔黑色TiO2 / MoS2 / TiO2纳米片用于可见光驱动的光催化
新型的3D中孔黑色TiO 2（MBT）/ MoS 2 / MBT三明治状纳米片成功地通过机械化学过程结合原位固态化学还原方法成功制备，然后在350℃下进行轻度煅烧（350°C）氩气气氛。MBT / MoS 2 / MBT呈现3D三明治状纳米片结构，并且异质结在MoS 2和黑色TiO 2之间的界面处形成。MBT / MoS 2 / MBT的带隙明显变窄归因于MoS 2的引入和形成的Ti 3+框架中的物种。甲基橙的可见光光催化降解率和制氢率分别高达89.86％和0.56 mmol h -1 g -1。在框架中引入MoS 2和Ti 3+有利于可见光吸收和光生电荷的分离，而3D三明治状异质结结构则有利于光生电荷的转移。
