NiFe2O4 OER Performance Data with Cr and Mn Doping via Hydrothermal Synthesis

A study by Davide Vendrame explores the optimization of spinel oxide NiFe2O4 for the oxygen evolution reaction through Cr and Mn doping. The dataset likely contains structural, surface, and electrochemical characterization results from XRD, TEM, XPS, and electrochemical investigations. It was last updated on 2026-04-21 and shared under a CC-BY-4.0 license.

Use Cases

• Correlating dopant chemistry with electrocatalytic performance based on the described structural and electrochemical analysis.
• Analyzing the effect of specific surface area on OER activity based on the reported values up to 226 m²/g.
• Comparing the formation of secondary phases in doped spinel oxides based on the mention of Ni(OH)2 in Mn-doped samples.
• Investigating the role of Cr³⁺ in modulating eg occupation for OER promotion based on the hypothesized synergistic effect.

Strengths

• Includes detailed structural and surface characterization data from XRD, TEM, and XPS.
• Reports specific surface area measurements up to 226 m²/g for Cr-doped samples.
• Compares electrochemical performance against a benchmark material (IrOX).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary data file is a DOCX document, which may require extraction of structured data.
