Recent graphene oxide/TiO₂ thin film based on self-cleaning application
(IOP Publishing Ltd, 2019-08)
Graphene oxide/TiO₂ (GO/TiO₂) thin films works as self-cleaning device have been developed in various method onto selected substrates. It was noticeable that graphene oxide is the best form in the group of graphene family. ...
Mesoporous structure of doped and undoped PEG on Ag/TiO₂ thin film
(IOP Publishing Ltd, 2019-08)
In this reaserch, photocatalyst silver titanium dioxide was doped and modified by Polyethylene Glycol (PEG). The purpose of the present study was to analyse the synthesized Ag/TiO₂ thin film doped and undoped PEG. Ag/TiO₂ ...
