One possible route is the photochemical reaction of metal ions in water to produce hydrogen and an oxidizer. The photooxidation of several low-valent transition metal ions, including europium(II), vanadium(II), and copper(I) complexes, proceeds in aqueous acidic media according to: Quantum yields...
Photoredox catalysis relies on light-induced electron transfer leading to a radical pair comprising an oxidized donor and a reduced acceptor in a solvent cage. For productive onward reaction to occur, the oxidized donor and the reduced acceptor must escape from that solvent cage before they undergo...
In solution, the photoredox process may be intermolecular, when the complex reacts with another species present in the solution but when the reaction takes place between the central atom and one of its ligand, then it is called intramolecular redox reaction. When a complex is irradiated, the ...
I didn’t mean uselowenergy light,” MacMillan recalls. But Nicewicz found a way to drive the reaction using a household compact fluorescent lightbulb. The trick was to use a visible-light-absorbing ruthenium bipyridyl catalyst, which was already a hot topic in solar cell research. ...
(e.g., electrochemistry) wherein the reaction medium can be either oxidative or reductive (but not both) and, in turn, provides access to previously inaccessible redox-neutral reaction platforms. Recent advances in modern photoredox catalysis have ...
