Photocatalysis: From Fundamental Principles to Materials and ...

WebAbstract. Photocatalysis as a green technology is essential to clean up water and environmental detoxification via visible light-induced photocatalysis and has various applications, such as CO2 reduction, organic contaminant degradation, removal of toxic ions and heavy metal ions, water-splitting, antibacterial, self-cleaning, etc. In chemistry, photocatalysis is the acceleration of a photoreaction in the presence of a photocatalyst, the excited state of which "repeatedly interacts with the reaction partners forming reaction intermediates and regenerates itself after each cycle of such interactions." In many cases, the catalyst is a solid that … See more Early mentions (1911–1938) The earliest mention came in 1911, when German chemist Dr. Alexander Eibner integrated the concept in his research of the illumination of zinc oxide (ZnO) on the bleaching of the … See more Photoactive catalysts have been introduced over the last decade, such as TiO 2 and ZnO nano rodes. Most suffer from the fact that they can only perform under UV irradiation … See more • Light harvesting materials • Photoelectrochemical cell • Photolysis • Photocatalytic water splitting • Photoredox catalysis See more Homogeneous photocatalysis In homogeneous photocatalysis, the reactants and the photocatalysts exist in the same phase. A intensively studied theme in homogeneous photocatalysis involves the destruction of ozone: 2 O3 → 3 O2 See more ISO 22197-1:2007 specifies a test method for the measurement of NO 2 removal for materials that contain a photocatalyst or have superficial photocatalytic films.
