摘要: Abstract The paper presents a study on the structural, surface and photocatalytic properties of ultrasound assisted sol-gel titanium dioxide particles, as part stable ink formulations deposited fabrics. activity was validated using methylene blue reference pollutant, under UV, VIS combined UV+VIS radiation allowed selecting optimum TiO 2 samples for inks preparation. To minimize particles agglomeration stabilizing agents were added stability quantitatively evaluated considering relative increase in transmittance pre-set period 30 min. Further on, ink(s) by cold spraying cotton woven fabrics removal efficiency higher than 95% observed degradation highly toxic mustard gas, after 30 min UV irradiation.
