Abstract

Nanoparticles of bare and PEG (Polyethylene glycol) capped zinc oxide (ZnO) were synthesized by precipitation method. The photocatalytic activity of bare and modified ZnO nanoparticles was studied by monitoring the degradation of Rhodamine B (RhB). The results show that PEG capped ZnO nanoparticles has reduced photocatalytic activity than the bare ZnO nanoparticles. The reduction in the chemical oxygen demand (COD) and total organic carbon (TOC) results also revealed the reduced photocatalytic activity of PEG capped ZnO. The UV-shielding property was evaluated by measuring the transmittance which shows that both bare and PEG capped ZnO nanoparticles possess good UV-shielding ability.
