Figure 1 (IMAGE) National University of Singapore Caption Figure showing the systematic design of the photocatalytic covalent organic frameworks (COFs) for manufacturing hydrogen peroxide using flow reactors. (a) The COF with segregated donor and acceptor zones along with specially designed water channels. (b) Under light, charges separate, with oxygen reduction occurring at one region, and water oxidation at another region. (c) Continuous production of hydrogen peroxide occurs in a flow reactor, where water and oxygen transform into hydrogen peroxide through the tiny channels of the photocatalyst.
