Herein, we report QS (quasi-spherical), IR (irregular), and NR (nanorod) Mn2OBO3 (manganese oxoborate), modified with a carbon support, as candidate electrocatalysts for OER in a neutral medium. QS-, IR- and NR-Mn2OBO3 catalysts displayed low onset potentials of 201 mV, 205 mV, and 208 mV and Tafel slope results of 94 mV dec(-1), 97 mV dec(-1), and 106 mV dec(-1), respectively. As a result of the long-term stability tests, it was determined that the NR-Mn2OBO3 sample was extremely stable compared to the QS- and IR-catalysts. This work introduces a new Mn2OBO3/C composite catalyst that displays efficient OER performance at a neutral medium and provides a different perspective for catalyst development strategies.eninfo:eu-repo/semantics/closedAccessBoratesElectrocatalysisManganese OxoborateOxygen Evolution ReactionWater OxidationArticle10.1002/cnma.202100256Q2WOS:0007063097000012-s2.0-85116886154Q2
