SYNTHESIS OF ZnO NANOMATERIALS ON BIOCHAR AND APPLICATION OF ANTIBIOTIC DEGRADATION IN AQUEOUS SOLUTION

Abstract

In this study, ZnO-biochar (RHZ) composites were synthesized to overcome the ZnO-related problems
(charge recombination, wider band gap, and poor visible light absorption) and improve the properties
and photocatalytic performance of carbon-based ZnO photocatalysts. The antibacterial level of
Sulfamethoxazole (SMZ) after treatment was checked by Bacillus subtilis activity. The research results
show that the photocatalysis material has a great ability to degrade SMZ as well as other antibiotic
residues in the water environment. RHZ composites can be used as stable, efficient, economical, and
sustainable composite for the recovery of pharmaceutical wastewater.
