'Holey' Nanosheets for Wastewater Dye Removal
Abstract:
Researchers have discovered that extremely thin sheets of nickel oxide with hexagonally shaped holes can absorb hazardous dyes from wastewater nearly as well as the best traditional methods, but are recyclable. The research was reported recently in the journal Nanotechnology.
The group, consisting of scientists from the Colorado School of Mines and South-Central University for Nationalities, in China, compared the performance of their nickel-oxide (NiO) "nanosheets" to the absorption properties of a powdered form of NiO as well as to activated carbon, a material often used for absorption applications because it has a very large overall surface area.
