Synthetic applications are limited at the moment, but some classes of useful reactions are emerging
Photocatalysis. A multi-faceted concept for green chemistry.
CHEMICAL SOCIETY REVIEWS, no. 7 (2009): 1999-2011
Photocatalysis (by semiconductors, molecules and ions) is used in such diverse applications as water hydrolysis for producing hydrogen as fuel, organic synthesis and the recovery of polluted effluents. This tutorial review discusses the common principles of such applications and their role in green chemistry.

- He moved to the Istituto Ronzoni (Milan) where he worked on the synthesis of peptidomimetics and functionalized chitosans and in 1998 returned to the University of Pavia where in 2008 was appointed associate professor.
- His interests lie in the application of photochemistry to organic synthesis encompassing photocatalysis and phenyl cation chemistry
- Photocatalysis is used in such diverse applications as water hydrolysis for producing hydrogen as fuel, organic synthesis and the recovery of polluted effluents
- Photosynthesis referred to reactions where part of the photon energy was incorporated in the products (that lay higher than the reagents on the potential surface, Davide Ravelli was born in 1984 and obtained his Master degree from the University of Pavia in 2008
- Angelo Albini and Maurizio Fagnoni. He spent a year studying the photostability of sunscreens. He worked on the decatungstate photocatalysis in a project sponsored by the INCA consortium and he’s working on mechanisms and effect of ionizing radiation on composite (Left to right) Angelo Albini, Maurizio Fagnoni, Davide Ravelli materials
- Maurizio Fagnoni graduated in Pavia in 1992 with a thesis on the synthetic applications of photo-SET reactions under the guidance of Prof

- Synthetic applications are limited at the moment, but some classes of useful reactions are emerging
- It has been demonstrated that the simplest organic molecule, methane, can be activated by silica, alumina, and silica-alumina photocatalysis under UV irradiation and converted to higher alkanes..
- The variety of reactions reported above, a limited choice from a very large number, are all based on the generation by light of a highly reactive species C*, such as a molecular excited state or charge pair in a semiconductor
- These species are able to activate a reagent by some chemical process that occurs under mild conditions, which would otherwise require a harsh procedure.
- The photodegradation of pollutants has been more largely developed and its practical significance demonstrated
- Indeed, it has been demonstrated that the simplest organic molecule, methane, can be activated by silica, alumina, and silica-alumina photocatalysis under UV irradiation and converted to higher alkanes (with the last catalyst 60% ethane formed up to 5.9% conversion).
