Fabrication of superwetting Cu@Cu2O cubic film for oil/water emulsion separation and photocatalytic degradation
Source abstract
Abstract
Abstract Facing the increasing oily wastewater problem and organic pollutants in the world, it is urgent to develop materials for efficient oil-water separation and water purification. Recently, various materials have been successfully synthesized for free oil/water separation. However, it is still a challenge for the separation of oil/water emulsion due to its small particle size. Herein, a superwetting and visible light catalytic Cu@Cu2O film was successfully prepared by one-step electrodeposition method. The as-prepared film showed underwater superoleophobic and underoil superhydrophobic after being pre-wetted by water and oil, respectively. Combining the unique super wettability and small pore size, the as-prepared film could be used to separate various water-in-oil emulsions and oil-in-water emulsions only under gravity and showed high separation efficiency. Due to the visible light responsive of Cu2O, the as-prepared sample could be applied to degrade organic contaminants. The degradation efficiency could reach 81.86% after 240 minute visible light irradiation. This newly as-prepared film is expected to have great potential in oil-water emulsion separation and organic contamination degradation.
