Reinforced Photoelectrochemical Properties of Nanostructural TiO2/C/SiO2 Integrated on Conductive Ti3SiC2

Herein, we constructed an ordered nanoporous embedding nanoparticles composite by anodic oxidation of Ti3SiC2 in fluorine containing organic electrolyte. Compared to anodized Ti which resulted in TiO2 nanotubes, the anodized Ti3SiC2 (ATSC) led to the formation of nanostructured TiO2/C/SiO2 composite. The morphologies of oxides in the composite also varied with different anodization parameters. The ATSC could be directly used as an electrode without further processes, which possessed a superior structure and composition with a visible-light photocurrent density of 7.56 mu A cm(-2), initial reversible area capacity of 6.18 F cm(-2), which were respectively 1.32 and 6.87 times higher than those of the anodized Ti (AT), respectively. The ATSC synthesized by such a feasible fabricating strategy shows favorable photoelectrochemical properties and remarkable stability, and may broaden the bifunctional material prospects of anodized MAX phases.
