Task 1.1 TiHO materials-synthesis and characterization

Synthesis method: Thermal treatment in argon atmosphere

TiHO materials were synthesis using TiO₂ Degussa P25 and TiO₂ sol-gel using titanium isopropoxide (TTIP), ethanol and HNO₃. The powder was thermal treated in different conditions, T=400....800°C, 6h in vid and Argon atmosphere.
