Herein, we propose an original material combination to selectively trigger oxygen evolution from seawater at expenses of chlorine generation. The target systems, based on MnO<sub>2</sub> or Mn<sub>2</sub>O<sub>3</sub> decorated with Fe<sub>2</sub>O<sub>3</sub> or Co<sub>3</sub>O<sub>4</sub>, are fabricated by plasma enhanced-chemical vapor deposition of manganese oxides, functionalization with Fe<sub>2</sub>O<sub>3</sub> and Co<sub>3</sub>O<sub>4</sub> by sputtering, and annealing in air/Ar to obtain Mn(IV)/Mn(III) oxides. Among the various options, MnO<sub>2</sub> decorated with Co<sub>3</sub>O<sub>4</sub> yields the best performances in alkaline seawater splitting, with an outstanding Tafel slope of ≈40 mV × dec<sup>−1</sup> and an overpotential of 450 mV, enabling to rule out chlorine evolution. These attractive performances, resulting from the synergistic contribution of catalytic and electronic effects, open the door to low-cost hydrogen generation from seawater under real-world conditions, paving the way to eventual large-scale applications.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Selective anodes for seawater splitting via functionalization of manganese oxides by a plasma-assisted process","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-05 01:31:23.456735","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Manganese oxides; Plasma enhanced-chemical vapor deposition; Sputtering; Oxygen evolution reaction; Seawater splitting","OtherDescriptors":null,"Notes":null,"AnaPub":2021,"MonPub":null,"DateUpdate":"2021-05-20","DateCreate":"2021-05-17","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000623591500008","VABBcode":null,"OpenAcc":0,"Handle":"10.1016/j.apcatb.2020.119684"},"refs":null,"anarec":{"AnaID":337224,"PubliDate":2021,"Pagination":"119684","XtraPublOfAnaID":null,"ISBN":null,"Volume":"284","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":258633,"SerRR":"Applied Catalysis B: Environmental.
