Abstract

Abstract : A conventional view is that particulate matter (PM) in the atmosphere is a major sink of OH radicals. By contrast, Xiao Cheng Zeng, Joseph S. Francisco, Hong He, and co‐workers demonstrate in their Communication (e202201638 ) that water and O2 react on carbonaceous soot surface and give rise to gaseous OH radicals under irradiation. This new chemical mechanism for the generation of OH radicals indicates that airborne soot particles possess important catalytic oxidation capacity.
