摘要： Mixed-valent MnO x (1 < x < 2) was selectively synthesized by chemically etching MnO and Mn 2 O 3 with ceric ammonium nitrate. The obtained MnO x exhibited greatly enhanced electrocatalytic activity toward the oxygen reduction reaction (ORR) as compared to the corresponding pristine oxides. Mixed-valent MnO x obtained by chemically etching MnO/Mn 2 O 3 with ceric ammonium nitrate exhibits enhanced electrocatalytic activity toward oxygen reduction. 出版日期： 2015-07-07 資源來源： Royal Society of Chemistry 識別號： ISSN: 1359-7345 識別號： EISSN: 1364-548X 識別號： DOI: 10.1039/c5cc03155a
