Abstract:MXene Ti3C2/ TiO2 hybrids were successfully synthesized through a simple calcination of F- terminated Ti3C2. The resultant Ti3C2/ TiO2 composite photocatalysts retained a 2D multilayer structure like MXene Ti3C2, and TiO2 exhibited a truncated octahedral bipyramidal structure with exposed ( 001) facets under the participation of fluorine ions. The residual Ti3C2 could act as a co- catalyst to enhance the photocatalytic H2 production activity by capturing photogenerated electrons from TiO2 because of its electron reservoir feature and suitable Fermi level. The ( 101)-( 001) surface heterojunction of the truncated octahedral bipyramidal TiO2 further accelerated the separation of photogenerated carriers. As a result, the Ti3C2/ TiO2 hybrids with calcining F- terminated Ti3C2 exhibited photocatalytic hydrogen production that is twofold higher than that of Ti3C2/ TiO2 hybrids with calcining OH- terminated Ti3C2. This work presented a new strategy to prepare MXene Ti3C2/ TiO2 hybrids for photoconversion applications.
