Abstract
Zinc oxide nanoparticles was synthesized by microwave decomposition of zinc acetate precursor. Horseradish peroxidase (HRP) was immobilized on nano-ZnO. The catalytic activity, physical, and chemical properties of immobilized HRP as well as the interaction between HRP and nano-ZnO was studied. The Nano-ZnO immobilized HRP showed a better property in the thermostability, active pH stability. The Nano-ZnO is more effective than free HRP in the removal of many phenolic compounds. The results show that nano-ZnO is strong functional materials for envrionment protection.
