IN these laboratories we have been carrying on experiments on photosynthesis in tropical sunlight for a number of years.1 We have been able to obtain formaldehyde by the exposure of solutions of carbonic acid and bicarbonates to tropical sunlight in presence of various inorganic and organic photocatalysts.

TLDR
A compilation of known reactions shows the extent of light-driven interactions between naturally occurring components of land, air, and water, and provides the backdrop for an outline of the mechanisms of these phenomena.

Photon-Driven Nitrogen Fixation: Current Progress, Thermodynamic Considerations, and Future Outlook

Over the last century, the industrialization of agriculture and the consumption of fossil fuels have resulted in a significant imbalance and redistribution in nitrogen-containing resources. This has

Formaldehyde in Rain Water

SINCE 1864, when Baeyer stated his formaldehyde hypothesis, numerous attempts have been made to obtain formaldehyde in vitro from carbon dioxide and water on exposure to light. Usher and Priestley,1

UNLESS qualified, the views of Prof. J. W. McBain,1 as well as those of Drs. Friend and Vallance,2 are apt to convey a wrong impression. Is the colloidal state always not essential in periodic
