| Abstract |
Preparation of natural-product-capped ZnO nanoparticles via a solvothermal method has been demonstrated. The stem extracts of Dalbergia parviflora namely formononetin and pinocembrin were used as capping agents for preparation of ZnO denoted as Capped-ZnO-1 and Capped-ZnO-2, respectively. The ZnO photocatalysts showed hexagonal structure with a spherical morphology and band gap energy of 3.22 eV. The Capped-ZnO-2 photocatalyst showed the smallest average diameters of 10 nm with the greatest specific surface area of 36.19 m2 g-1. The photocatalyst provided 100 % and 98 % removal of RR141 dye and OFL antibiotic, respectively, due to high surface area and high charge-carriers separation rate at the interface. The photocatalyst showed structural stability after three successive runs. The photocatalyst also showed the same performance after three times of use indicating its advantage of good cycling ability. The present work demonstrates the promising potential of the ZnO photocatalyst for environmental remediation. |
