Solar chemistry

For the transportation sector the goal is the production of solar fuels, which in the long term could replace oil and natural gas-based products. For photochemical and photocatalytic applications the aim is to substitute expensive artificial light with solar radiation, thus avoiding expenditure on electricity, cooling and light sources. Applications would be possible in a wide field of recycling processes as well. Industrial wastewater can be detoxified using solar photocatalytic technology, and particular problems relating to non-biodegradable contaminants can be solved. The solar sterilization of water without the addition of chemicals like chlorine would also be possible. In future, solar high-temperature process heat could be applied to the recycling of secondary metals, like aluminium, or for the vitrification of filter dusts. Altogether, a wide range of applications for solar chemistry is expected.
