标题： Black TiO2 nanotubes formed by high energy proton implantation show noble-metal-co-catalyst free photocatalytic H2-evolution

摘要： 我们应用高能质子离子注入，在TiO2纳米管的顶部选择性地对其进行改性。 在质子注入区域，我们观察到光催化产氢的本征共催化剂中心的形成。 我们发现质子注入会在纳米管以及金红石单晶(001)表面引起特定缺陷和电子性质的特征性改变。 然而，对于TiO2纳米管，可以得到注入区域（催化剂）与无注入管段（吸收体）之间的强烈协同效应。 显示英文摘要

摘要： We apply high-energy proton ion-implantation to modify TiO2 nanotubes selectively at their tops. In the proton-implanted region we observe the creation of intrinsic co-catalytic centers for photocatalytic H2-evolution. We find proton implantation to induce specific defects and a characteristic modification of the electronic properties not only in nanotubes but also on anatase single crystal (001) surfaces. Nevertheless, for TiO2 nanotubes a strong synergetic effect between implanted region (catalyst) and implant-free tube segment (absorber) can be obtained.
