Description
Summary:Preparation of TiO2/Ti3C2 by in-situ oxidation with a green method. [Display omitted] •TiO2/Ti3C2 was prepared by in-situ oxidation with a green method.•A heterojunction interface formed between the anatase phase TiO2 and the Ti3C2.•The highest H2 production performance is 2520.4 μmol·g−1·h−1. The preparation of high-efficiency photocatalysts by green and mild methods is very attractive for photocatalysis field. Here, TiO2/Ti3C2 was prepared by in-situ oxidation with a green method, in which only water or H2O2 was used. A heterojunction interface formed between the anatase phase TiO2 and the Ti3C2, which was demonstrated by HRTEM and XRD. Fluorescence spectra and i-t transient photocurrent are used to study the separation efficiency of photogenerated electron-hole pairs. The close contact between Ti3C2 and TiO2 speed up the separation of photo-generated electron-hole pairs, promoting a higher hydrogen production performance around 2520.4 μmol·g−1·h−1 on TCT-1.
