A novel three-dimensional catalytic nanodiode composed of a Pt thin film on TiO nanotubes was designed for the efficient detection of the flux of hot electrons, or chemicurrent, under hydrogen oxidation. We verify a significant increase in the chemicurrent from the fast transport of electrons across the ordered supporting oxide layer. This study demonstrates the direct detection of hot electrons on well-ordered TiO nanotubes during the catalytic reaction.
设计了一种新型的三维催化纳米二极管，由 TiO 纳米管上的 Pt 薄膜组成，用于高效检测在氢气氧化下热电子（或化学电流）的通量。我们验证了电子通过有序支撑氧化层的快速传输导致化学电流显著增加。该研究在催化反应过程中直接检测到了在有序 TiO 纳米管上的热电子。
