Adsorption and photo-catalytic properties of layered lepidocrocite-like quasi-amorphous compounds based on modified potassium polytitanates

- Quasi-amorphous potassium titanate nanoparticles were modified in transition metal salt solutions.
- PPT particles were modified through metal ion intercalation and/or metal oxides decoration.
- Studied systems support degradation of organic dye under visible light irradiation.
- Photocatalytic properties are described by multiple p-n junctions and decreased band gap energy.
