Hydrogen　peroxide　has　significant　applications　across　various　sectors,　including　industry,　healthcare,　and　wastewater　treatment.　NiTe　nanomaterial　has　been　synthesized　using　a　facile　aqueous-phase　method　in　this　work.　Specifically,　5　mmol　of　nickel　acetate　tetrahydrate　(Ni(CH3COO)2•4H2O)　was　dissolved　in　deionized　water　and　reacted　with　10　mmol　of　tartaric　acid　to　form　solution　A.　Simultaneously,　5　mmol　of　tellurium　dioxide　powder　was　heated　in　10　mmol　of　ammoniated　tartaric　acid　to　prepare　solution　B.　Both　solution　A　and　B　were　adjusted　to　a　pH　value　of　10.　Solution　B　was　gradually　introduced　into　solution　A　under　continuous　agitation　to　ensure　homogeneous　mixing.　Subsequently,　7.5　mmol　of　sodium　borohydride　(NaBH4)　was　added　to　the　mixture　under　vigorous　mechanical　stirring,　resulting　in　the　formation　of　a　black　NiTe　precipitate.　The　research　results　indicate　that,　using　oxygen　and　pure　water　as　raw　materials,　and　employing　porous　cation　exchange　resins　as　solid-state　electrolyte　in　the　electrolyzer,　the　Faradaic　efficiency　of　H2O2　reaches　85%　at　a　potential　of　0.31　V　(vs.　RHE)　and　maintains　a　Faradaic　efficiency　of　over　80%　within　a　potential　window　of　200　mV.　Additionally,　at　0.11　V　(vs.　RHE),　the　H2O2　production　rate　can　reach　4334.39　mmol•h−1•g−1.　In　stability　assessments,　the　NiTe　catalyst　exhibited　continuous　and　stable　H2O2　production　for　over　6　h.　The　electronic　structure　modulation　effect　of　Te　in　the　NiTe　catalyst,　combined　with　abundant　grain　boundaries　and　defect　sites,　as　well　as　the　small　particle　size　and　hybrid　porous　structure,　provides　ideal　active　centers　and　excellent　structural　foundation,　which　endows　NiTe　with　excellent　catalytic　performance.　The　application　of　solid-state　electrolyte　devices　not　only　significantly　reduces　costs　and　operational　risks　but　also　enables　the　direct　production　of　pure　hydrogen　peroxide　solution,　thereby　improving　production　efficiency.　This　research　offers　a　new　approach　for　the　efficient　electrochemical　production　of　hydrogen　peroxide　from　oxygen.　©　2025　Shanghai　Institute　of　Organic　Chemistry,　Chinese　Academy　of　Sciences.
