Study of chemical and electrochemical processes influencing growth of self-organized TiO2 nanotubes in solutions
Provider: Grantová agentura ČR
Programme: Standardní projekty (řešení od 1.1.2014)
Implementation period: 01.01.14 - 31.12.15
Workplace:
Fakulta chemicko-technologická - CEMNAT
Investigator: Macák JanTeam member: Knotek Petr
Description:
The project focuses on investigations of chemical and electrochemical conditions that lead to highly ordered self-organized TiO2 nanotube layers prepared by anodization of Ti in suitable electrolytes. The enhancement of the lateral ordering gives great promise for enhancement of various properties of tinania nanotube layers that in turn can be used more efficiently for many functional applications, including photocatalysis, water splitting, solar cells. The main focus of the project is given on the electrolyte chemistry and search for the right electrochemical condition, since the electrolyte chemistry is the main factor influencing the growth of nanotube layers. The goal of the project is to identify such conditions that lead to the growth of ordered layers and have not been properly investigated and understood till now. We aim also towards synthesis of novel shapes of anodic TiO2 nanotubes with improved degree of ordering and highly ordered patterns, using Ti substrates with distinct surface locations by various lithographic techniques or indentation techniques
