Solvated　electrons　have　attracted　increasing　research　interest　due　to　their　strong　reducing　ability.　However,　the　generation　and　utilization　of　solvated　electrons　in　photocatalytic　systems　are　rarely　reported　owing　to　the　challenges　in　synthesis　and　their　complex　structures.　Here,　we　present　a　photocatalytic　system　by　accessing　laboratory-scale　concentrations　of　ammoniated　electrons.　Under　visible　light　irradiation,　ammoniated　electrons　are　achieved　by　a　cyanamide　functionalized　and　potassium　heptazine　based　melon　polymer　(PC-HM)　in　the　presence　of　an　electron　donor,　which　are　stable　for　days.　This　PC-HM　can　produce　ammoniated　electrons　at　room　temperature　to　reduce　dioxygen,　thus　enabling　the　production　of　H2O2　coupled　with　the　selective　oxidation　of　alcohols　under　visible　light　illumination.　This　work　presents　the　possibility　to　take　advantage　of　ammoniated　electrons　for　solar　energy　conversion　in　energy　and　advanced　organic　chemistry.　Copyright　©　2019　American　Chemical　Society.
