Performance of TiO 2 /Al 2 O 3 /carbon nanotube nanocomposite on the photocatalytic degradation of metamifop

The photocatalyst of TiO 2 /Al2O 3 /CNT nanocomposite was prepared by hydrothermal process. Its performance was evaluated based on the efficiency in degrading metamifop, an active ingredient in the commercial formulation herbicide. The effect of initial concentration metamifop, the dosage of photoca...

Description
Summary:The photocatalyst of TiO 2 /Al2O 3 /CNT nanocomposite was prepared by hydrothermal process. Its performance was evaluated based on the efficiency in degrading metamifop, an active ingredient in the commercial formulation herbicide. The effect of initial concentration metamifop, the dosage of photocatalyst used during photocatalytic degradation of metamifop and the effect of air flow rate were investigated for the evaluation of its performance. The highest percentage degradation of 10 mg/l metamifop obtained from this study was 95.0% using 20 mg of TiO 2 /Al 2 O 3 /CNT nanocomposite photocatalyst with the air flow rate of 2 l/min. The prepared photocatalyst can be potentially used in environmental application.
