Facile fabrication of a novel pyridinelyethyne/titanium dioxide nanotube hybrid with high photoelectronic performance

Abstract A novel and facile approach for preparing a new type of nanohybrid (TNTs-Cr3+-DPyE) was explored by anchoring 1,2-di(pyridine-4-ly)ethyne (DPyE) in the chromium ions implanted TiO2 nanotube (TNTs) by coordination interaction. Subsequently, a wider optical absorption range and an improved electron transfer were achieved in the nanohybrid, which were profitable for improving the photoelectronic performance of the TNTs. The results showed the important role of Cr3+ in improving the light absorption and the electron transfer between TNTs and DPyE. This work developed a simple way to design and prepare highly active TNTs-based photoelectronic materials.
