Activated charcoal modified Ag and Cu-anatase TiO 2 for superior photocatalytic degradation of doxycycline under visible-solar light irradiation

Key Points

• The study aims to evaluate the impact of activated charcoal and metal loading on the photocatalytic properties of TiO2 in degrading doxycycline.
• Used activated charcoal and Ag/Cu loading to modify TiO2
• Evaluated photocatalytic performance under visible and solar light conditions
• Measured degradation rates of doxycycline compared to unmodified TiO2
• Cu2TC1 composite achieved 98.5% degradation of doxycycline under sunlight
• Bare TiO2 only achieved 68.7% degradation
• Significant improvement in photocatalytic efficiency due to composite modification
