摘要	A novel carbon/silica co-decorated TiO2 nanotubes (TNT) photocatalyst (CS@TNT) was prepared for visible light driven water splitting by a facile two-steps process of amino-propyl-triethoxy silane modification and calcination. Structure characterizations (XRD, STEM, XPS, UV-vis spectra and PL spectra) revealed that the silica and carbon dots were homogeneously dispersed on the surfaces of TNT. The introduced silica resists crystallization of TNT, and keeps the tubular morphology intact and high surface area; the co-existence of carbon dots increases the visible light absorbance capacity and promotes the electron-hole separation efficiency. The CS@TNT preserves intact tubular morphology during calcination (500 degrees C), and a high activity of 0.096 mmol/h is achieved, which was 1.7 times higher than that of actual catalyst made of gold nanoparticles loading on TNT.
