Novel nanoporous silver particles for electro-reduction of hydrogen peroxide in alkaline media

► Novel nanoporous silver particles (nanoAg) were hydrothermally prepared. ► Electro-activity of the nanoAg towards H2O2 reduction in alkaline media was assessed. ► Extremely high stable reduction current of H2O2 on the nanoAg catalyst. ► Significantly low charge transfer resistances for H2O2 reduction on the nanoAg.
