How It Compares
Within the oxide oxygen-evolution catalysts class.
While many members of the oxide oxygen-evolution catalyst class, such as LiCoO2 or LaMnO3, are widely utilized in battery electrodes and perovskite-based catalysis, Mn2Te3O8 represents a distinct chemical space involving tellurium. Unlike the more common transition metal oxides like NiO or LiMn2O4, this compound offers a different electronic landscape that researchers investigate to expand the library of stable, semiconducting materials available for catalytic applications.
