Photoreduction of cytochrome c1

Journal of Biological Chemistry, 1975
1. Ferricytochrome c1 solution was reduced completely between pH 7 and 10 by illumination under anaerobic conditions. Photoreduction was not affected by the ionic strength of the medium. However, it did not take place at pH lower than 6 or higher than 10, or in the presence of p-hydroxymercuric benzoate.

Ionic Liquid-Modified Porous Organometallic Polymers as Efficient and Selective Photocatalysts for Visible-Light-Driven CO2 Reduction

Research, 2020
In the photoreduction of CO2 to CO, the competitive H2 evolution is always inevitable due to the approximate reduction potentials of H+/H2 and CO2/CO, which results in poor selectivity for CO production.
