UV-resistant hydrophobic CeO2nanomaterial with photocatalytic depollution performance
Hydrophobiccerium dioxide(CeO2)nanomaterial, consisting of numerous open-endednanotubes, was synthesized via a hydrothermal method without further chemical modification. The as-synthesized material displays water contact angle (CA) as high as 120°. Thismetal-oxidesemiconductorshows a good long-term durability and excellent photocatalytic ability for the removal of salad oil under UV lightirradiation. Thehydrophobicitycan be regenerated after contamination with salad oil due to the photocatalytic activity. In addition, this CeO2nanomaterial presents good repellence to hot water droplets.
