Abstract
The present teachings describe photocatalytic composite materials that are useful for remediation of bodies of water such as lakes, ponds, wetlands and rice fields, as well as remediation of sediment under the water.
Claims20
A method of water and sediment remediation comprising:
- contacting a photocatalytic composite material comprising titanium dioxide particles and silver particles associated with a polyelectrolyte in a solvent, with a body of water in need of remediation and containing sediment in need of remediation;
- and
- exposing the photocatalytic composite material to visible light and/or sunlight for a suitable time and under conditions suitable for the photocatalytic composite material to cause contaminant compounds in the body of water to be transformed into one or more different compounds, and to cause a decrease in the sediment in the body of water.
A method of reducing methane emissions during water remediation comprising:
- contacting a body of water with the photocatalytic composite material comprising titanium dioxide particles and silver particles associated with a polyelectrolyte in a solvent;
- and
- exposing the photocatalytic composite material to visible light and/or sunlight for a suitable time and under conditions suitable for the photocatalytic composite material to cause a reduction in methane emissions from the body of water compared to methane emissions from the body of water not treated with the photocatalytic composite material.
A method of sediment remediation comprising:
- contacting a photocatalytic composite material with a body of water containing sediment in need of remediation, wherein the photocatalytic composite material comprises titanium dioxide particles and silver particles associated with chitosan;
- and
- exposing the photocatalytic composite material to visible light and/or sunlight for a suitable time and under conditions suitable for the photocatalytic composite material to cause a decrease in the sediment in the body of water.
