High photocatalytic efficiency of inkjet printed patterns by formulation of eco-friendly TiO2-based inks

High photocatalytic performances of inkjet printed patterns has been achieved by a green formulation of water-based suspension including commercial TiO2 nanoparticles (NPs). The reaction rate constant (k > 3.79 × 10−3min−1cm-2) of the manufactured patterns presented competitive photoresponses in...
