6.2.4 Additional demand for research

(Photo)Catalysis

• Development of (photo)catalysts with higher photocatalytic efficiency which can use a higher percentage of the incoming photons e.g. due to doping with (noble)metals
• Development of (photo)catalysts which can use a wider spectrum of wave lengths e.g. due to doping with (noble)metals
• Investigation of pollutant conversion and release of by-products
• Understanding of dynamic mode of the photocatalysis, influence of light intensity/spectrum on the photocatalytic efficiency and the effect on multicomponent mixtures of pollutants (benzene, acetaldehyde, formaldehyde, CO and NO2, xylenes, naphtalene, styrene, toluene, a-pinene, d-limonene)
• Prohibit the oxidation of the organic matrix in which TiO₂ is embedded and of the material which is coated by the photocatalytic material.
• Possible agglomeration of photocatalytic particles within a fixed structure and consequent change of physicochemical properties (e.g. through functionalisation)
• Immobilisation of the nanoparticles in the coating to avoid particle release over time (long term testing of nanomaterials)
• Develop standards and analytical methods for the testing of photocatalytic applications to allow a comparision of the efficiency of different products.
• Ensure that silica may not inhibit the photocatalytic activity of titanium dioxide
