Provider: Grantová agentura ČR

Description:
The project focuses on the synthesis of large area anodic TiO2 nanotube layers (TNTs) and their subsequent modification to increase their photoelectrochemical activity. For understanding of the structure-property relationship, the resulting TNTs will be tested for liquid and gas phase photocatalysis and virus killing. There are two objectives: i) development of anodization protocols allowing to produce TNTs on large areas (?50 cm2) with adjustable nanotube dimensions; ii) the utilization of developed TNTs for the photocatalytic degradation of volatile organic compounds (e.g. toluene, acetaldehyde) and viruses. To use a greater part of the solar spectrum (including the visible light), the TNTs will be modified with secondary materials using Atomic Layer Deposition (to produce homogenous thin coatings) and using hydrothermal methods (to decorate TNTs by nanoparticles). The main motivation of the project is to explore the synthesis of TNTs on the large area, which is so far not feasible, yet highly challenging. The project outputs will bring the TNTs closer to applications in catalysis.
