Cellulose acetate or polyvinylpyrrolidone is electrospun into fibers having diameters of nanometer scale to form a first mat that is capable of absorbing hydrocarbons. A second mat may be formed from a solution of cellulose acetate or polyvinylpyrrolidone further containing tungsten trioxide. The solution is electrospun onto a copper mesh and then thermally oxidized to create a nanostructure comprising a grid or network of tungsten trioxide crystals and copper oxide crystals. The nanogrid is capable of photocatalyzing the degradation of hydrocarbons to carbon dioxide and water. The grid may be combined with the first mat to degrade hydrocarbons that the first mat absorbs.
A system comprising:
A product comprising an untreated, non-woven mat comprising nanofibers, wherein said mat further comprises an oil absorbed from an oil-contaminated surface of a body of water.
A method of removing an oil from a surface contaminated with oil, the method comprising disposing untreated, electrospun nanofibers comprising cellulose acetate onto said surface.
A method of recovering an oil from a surface contaminated with oil, the method comprising the steps of a) disposing an untreated, non-woven mat of untreated, electrospun nanofibers comprising cellulose acetate onto said surface to absorb said oil, creating an oil-containing mat;
A photocatalytic nanogrid comprising a composite of at least two metal oxides.
A method of fabricating a composite comprising CuO and WO3, said method comprising the steps of:
