High capacity mercury adsorption on freshly ozone-treated carbon surfaces
TLDR
The combined results suggest that the ultra-high mercury capture efficiency is due to a subset of labile C-O functional groups with residual oxidizing power that are likely epoxides or (epoxide-containing) secondary ozonides, opening the possibility for in situ ozonolysis to create high-performance carbon-based Hg sorbents.About:

Mechanism of Ozonolysis
TL;DR: The formation of ozonides (1,2,4-trioxolanes) from alkenes and ozone can be described as a succession of three [2+3] cycloadditions or cycloreversions involving primary ozone oxides and aldehyde or ketone oxides as decisive intermediates as mentioned in this paper.
