  • A facile approach was developed to construct Fe2O3-modified ZnO micro/nanostructures with excellent superhydrophobicity and photocatalytic activity. The impacts of stearic acid (SA) and Fe2O3-modified on the morphology, water contact angle (WCA) and photocatalytic degradation were investigated. The superhydrophobic results showed increased of WCA from 144 ± 2° to 154 ± 2° when SA weight increase from 5 mg to 20 mg due to formation of hierarchical or rough structure. Furthermore, Fe2O3-modified ZnO micro/nanostructures surface before and after treatment with SA (20 mg) chosen to evaluate the photocatalytic of Methylene blue (MB) dye by supporting visible-light. The results showed degradation of MB after 80 min of irradiation with photodegradation efficiency 91.5% for superhydrophobic state and 92% for the hydrophilic state. This improvement in photocatalytic activity at both states may be attributable to an increase of surface area and improve charge carriers separation.

Preparation and photocatalytic property of Fe2O3/ZnO composite with superhydrophobicity

Abstract: A facile approach was developed to construct Fe2O3-modified ZnO micro/nanostructures with excellent superhydrophobicity and photocatalytic activity. The impacts of stearic acid (SA) and Fe2O3-modified on the morphology, water contact angle (WCA) and photocatalytic degradation were investigated. The superhydrophobic results showed increased of WCA from 144 ± 2° to 154 ± 2° when SA weight increase from 5 mg to 20 mg due to formation of hierarchical or rough structure. Furthermore, Fe2O3-modified ZnO micro/nanostructures surface before and after treatment with SA (20 mg) chosen to evaluate the photocatalytic of Methylene blue (MB) dye by supporting visible-light. The results showed degradation of MB after 80 min of irradiation with photodegradation efficiency 91.5% for superhydrophobic state and 92% for the hydrophilic state. This improvement in photocatalytic activity at both states may be attributable to an increase of surface area and improve charge carriers separation.
