Abstract
Wood is treated with at least one photocatalytically degradable organic substance, organic compound or at least one biocide to reduce the contamination by organic substances, organic compounds and/or biocides from wood or wood-base materials into the immediate surroundings, in particular in closed spaces. The wood treatment agent contains at least one photocatalyst which brings about the degradation of the at least one organic substance, organic compound and/or the at least one biocide. The application/introduction of the at least one photocatalyst to or into the wood can take place together with or after the introduction of the wood preservation agent.
Claims12
A wood treating agent comprising a wood preservative having at least one organic substance, organic compound, or biocide, or any combination thereof, wherein the at least one organic substance, organic compound, or biocide is photocatalytically degradable, said wood preservative including at least one photocatalyst causing degradation of the at least one organic substance, organic compound, or biocide, or any combination thereof, said at least one photocatalyst including titanium dioxide (TiO2), carbon-doped TiO2, nitrogen-doped TiO2, or nitrogen-doped TiO2 having palladium nanoparticles.
A method of treating wood or wood-based materials comprising:
- applying a wood preservative including at least one biocide to the wood or introduced thereinto;
- applying to or into the wood at least one photocatalyst which can cause degradation of the at least one biocide, the application of the at least one photocatalyst taking place together with or after the application of the wood preservative, said at least one photocatalyst including titanium dioxide (TiO2), carbon-doped TiO2, nitrogen-doped TiO2, or or nitrogen-doped TiO2 having palladium nanoparticles.
Wood or wood-based material having a wood preservative including at least one biocide, wherein the at least one biocide is photocatalytically degradable and the wood includes at least one photocatalyst which can cause degradation of the at least one organic substance, organic compound, or biocide, said at least one photocatalyst including titanium dioxide (TiO2), carbon-doped TiO2, nitrogen-doped TiO2, or nitrogen-doped TiO2 having palladium nanoparticles.
A method of degrading biocides in wood having at least one biocide, said method using photocatalysts, said photocatalysts including titanium dioxide (TiO2), carbon-doped TiO2, nitrogen-doped TiO2, or nitrogen-doped TiO2 having palladium nanoparticles.
