Heterogeneous photochemistry relevant to the troposphere: H(2)O(2) production during the photochemical reduction of NO(2) to HONO on UV-illuminated TiO(2) surfaces.
Bleached out: The detection of an oxidized co-product, hydrogen peroxide, during an important tropospheric reaction, combined with the detection of photoaccelerated surface nitrate formation (a competing pathway), allows a likely mechanism to be proposed (see figure) which explains previously observed experimental stoichiometries.
