最少的就是最好的。我们引入了一种技术，可以大大减少 TiO2 纳米管光催化制氢中 Pt 的使用。通过仅在纳米管口处选择性地沉积 Pt 薄层以及随后的热去湿步骤，我们以最少量的助催化剂实现了出色的光催化改进。
The least is the best. We introduce a technique to strongly reduce Pt use for photocatalytic hydrogen generation from TiO2 nanotubes. By site-selectively depositing thin layers of Pt only at the mouth of the nanotubes and by a subsequent thermal dewetting step, we achieve an outstanding photocatalytic improvement with minimal amounts of co-catalyst.
