Unraveling the role of chitosan in enhancing the photodegradation of ciprofloxacin by using chitosan-titanates composites: Experimental and in-silico approach.

A hybrid composite (inorganic-organic) based on chitosan-functionalized hydrogen titanate nanotubes (TiCH) was synthesized by the hydrothermal method assisted by microwave, during 5h at 150 °C. The in-silico analysis determined the possible chitosan chemical adsorption models after calculating the Gibbs energies of their HOMO-LUMO orbitals. The TGA analysis confirmed the stability and helped to obtain the real functionalization degrees for the 3TiCH (2.

Adsorption and photocatalytic-conjugated activity of a chitosan-functionalized titanate coating for the removal of the drug clonazepam from drinking water.

This research evaluated HTiO nanotubes (TiNTs) functionalized with 1 (1TiCN), 5 (2TiCN), and 10 (3TiCN) wt.% of chitosan for the removal of clonazepam by an adsorption/photocatalysis-conjugated method. The samples were immobilized on glass, and their mechanical stability was tested by washings.
