In this study, we demonstrate that the addition of ascorbate can lower the conversion percentage of H2O2 to O2 from 71% to 11%, and thus increase the conversion percentage of H2O2 to [rad]OH from 11% to 82% on goethite within 3 h. This greatly enhanced production of [rad]OH could be attributed to the efficient Fe(III)/Fe(II) redox cycle accelerated by ascorbate, which produced abundant Fe(II) confined on the goethite surface, favoring the conversion of H2O2 to [rad]OH. Meanwhile, the decreased surface Fe(III) of goethite strongly inhibited the ...
