Abstract
|
Researchers
designed a simple aqueous solution-immersion process to fabricate highly
dense ordered Cu2O nanorods on commercial phosphor-copper mesh, with which
the preparation was accomplished in distilled water. The method, with the
advantages of simple operation, low cost, short reaction time, and
environmental friendliness, can be used to fabricate desired Cu2O
nanostructures on the phosphor-copper mesh under mild conditions.
After surface modification with 1-dodecanethiol, the Cu2O nanostructure obtained on the phosphor-copper mesh exhibits excellent superhydrophobicity and superoleophilicity. Besides, a mini boat made from the as-prepared superhydrophobic phosphor-copper mesh can float freely on water surface and in situ collect oil from water surface. This shows that the facile, inexpensive and environmentally friendly approach could be used for oil/water separation and off shore oil spill cleanup. |
