Definition of photocatalysis in English:
photocatalysis
noun ˌfəʊtə(ʊ)kəˈtalɪsɪsˌfoʊdoʊkəˈtæləsəs
mass nounChemistry The acceleration of a chemical reaction by light.
Example sentencesExamples
- In the area of photocatalysis, developing colloidal semiconductor systems capable of converting visible light to a useful form of energy has also been the center of attention.
- This investigation is exciting because it promises to provide fundamental scientific breakthroughs in chemical synthesis, self-assembly, electron and energy transfer processes, and photocatalysis.
- Nevertheless, the system does demonstrate for the first time the decontamination of a bacteria-containing air stream by photocatalysis at room temperature.
- Other potential applications for photocatalysis plants could include train toilets, or around sewage and waste treatment facilities.
- The photocatalysis effect comes about because TiO 2 is a semiconductor that can absorb the high-energy component of sunlight.
Derivatives
adjective
Chemistry The result of several years' research, the product incorporates a proprietary dual-action coating, using hydrophilic and photocatalytic properties to eliminate water and organic and inorganic deposits from the surface of the glass.
Example sentencesExamples
- This layer functions in two ways: having both photocatalytic and hydrophilic effects.
- The coating is hydrophilic and photocatalytic; i.e., it causes rainwater to sheet on the surface and it oxidizes dirt and organic deposits, breaking their adherence to the glass.
- The resulting porphyrin nanotubes have ‘interesting electronic and optical properties such as an intense resonance light scattering ability and photocatalytic activity.’
- The new Pilkington Activ glass is photocatalytic which means UV rays react chemically with dirt and organic deposits such as bird lime, breaking them down and loosening them from the surface of the glass.
