Novel homogeneous photocatalyst for oxygen to hydrogen peroxide reduction in aqueous media

Photochem Photobiol Sci. 2019 Aug 1;18(8):1982-1989. doi: 10.1039/c9pp00206e. Epub 2019 Jun 25.


An isoquinolinium-pyrrole donor-acceptor dyad was found to exhibit photocatalytic activity in oxygen-to-peroxide photoreduction with oxalate as a sacrificial electron donor. The concentration of hydrogen peroxide was shown to reach a plateau of 0.57 mM. The screening of related pyridinium-pyrrole dyads showed the importance of the isoquinoline moiety in securing the photocatalytic activity.
