Abstract
In order to prepare highly efficient and stable photocatalytic hydrogen production catalyst, spot-coated carbon nanotube (CNT) composites were prepared by in situ growth of TiO2 on the surface of CNT by adding CNT in four butyl titanate and then sol–gel method under ultrasonic irradiation. Compared with the nanocomposites doped with dopamine, the prepared nanocomposites obviously had lower agglomerated degree and showed excellent hydrogen evolution performance. The optimal hydrogen production performance was 0.0337 mg/ml for the prepared nanocomposites, which had a stable photocatalytic efficiency.
