Overview

About Mn3OF5

Mn3OF5 is a unique semiconducting oxyfluoride that occupies a specialized niche within the broader family of oxide-based oxygen-evolution catalysts. Its structural complexity and metastable nature make it a subject of significant interest for researchers investigating non-traditional catalytic pathways in electrochemical systems. By incorporating fluorine into the manganese oxide framework, this compound offers distinct electronic properties that differentiate it from standard binary oxides. Its presence in numerous structural databases underscores its importance as a model system for understanding phase stability and catalytic performance in complex inorganic materials.

Frequently Asked Questions

Common questions about Mn3OF5, answered from cross-validated data.

What is Mn3OF5?

Mn3OF5 is a metastable semiconducting oxyfluoride material investigated for its potential utility in electrochemical oxygen-evolution catalysis.

More questions
What is Mn3OF5 used for?
Mn3OF5 is used in oxygen-evolution catalysis and electrochemical energy storage research.
What is the band gap of Mn3OF5?
Mn3OF5 has a DFT-computed band gap of 0.04 eV across 53 reported structures. Standard DFT underestimates band gaps, so the measured gap is typically larger.
Is Mn3OF5 a metal, semiconductor, or insulator?
DFT predicts a near-zero band gap ((semi)metallic). Standard DFT underestimates gaps, so the real material may be a semiconductor.
Is Mn3OF5 thermodynamically stable?
Yes — Mn3OF5 sits on the convex hull (energy above hull 0 eV/atom), i.e. stable.
What is the crystal structure of Mn3OF5?
The reference structure of Mn3OF5 is monoclinic symmetry, space group C2/m (No. 12).
How many polymorphs of Mn3OF5 are known?
53 structures of Mn3OF5 are reported across 2 databases, spanning 9 distinct space groups.
What elements does Mn3OF5 contain?
Mn3OF5 contains F, Mn, and O (3 elements).
Where does the data for Mn3OF5 come from?
Mn3OF5 data is cross-referenced from jarvis, materials_project.
Comparison

How It Compares

Within the oxide oxygen-evolution catalysts class.

While traditional catalysts like NiO and LaMnO3 are well-established, highly stable oxides, Mn3OF5 represents a more exotic, metastable alternative that challenges conventional design paradigms. Unlike the layered lithium-based intercalation materials such as LiCoO2 or LiNiO2, this compound utilizes an oxyfluoride lattice to potentially tune the electronic environment for catalytic activity, positioning it as a distinct, experimental counterpart to the more common perovskite-structured oxides like LaNiO3.
