Photochemistry and photocatalysis
Rendiconti Lincei, 2016Photocatalysis is an important branch of catalysis and much more than that. To understand the potential applications and the working mechanisms of photocatalysis, it is necessary to know some important concepts of photochemistry, the branch of science that deals with the interaction of light and matter: (1) light excitation with a photon of suitable ...

Photochemistry of Photosynthesis
1991Publisher Summary Photosynthesis is composed of many individual steps that work together with high overall efficiency. The process can be divided three stages: the photochemical steps, electron transfer to which is coupled ATP formation, and the biochemical reactions involving the incorporation of CO2 into carbohydrates.

Atmospheric Environment (1967), 1987
Ozone plays a major role in the atmosphere, important chemical transformations in the troposphere, stratosphere, and mesosphere all being initiated by the absorption of radiation by ozone. This article surveys laboratory data concerning the photochemistry of ozone, and indicates the relevance of the laboratory studies to interpretations of atmospheric ...

Publisher Summary This chapter describes the important photochemical reactions that occur in the atmosphere and that are significant for the nature of our environment. Anthropogenic emissions of oxides of nitrogen, and hydrocarbons from internal combustion automobile engines and stationary furnaces are major contributors to photochemical reactions in ...

The photochemistry of the paleoatmosphere
Journal of Molecular Evolution, 1982The ideas of Harold Urey on the origin and evolution of the atmosphere have dominated thinking in this area for 3 decades. Recent progress in this area is reviewed, with particular emphasis on photochemical modeling studies of atmospheric evolution. Research into the paleoatmosphere can be divided into 3 distinct areas: (1) The photochemistry/chemistry
