Electrocatalyst Performance Data for Oxygen Evolution Reaction

A 190.6 KB document authored by D. J. Patil and last updated on 2026-04-28. It describes the synthesis and performance of nickel tungstate (NiWO4) and reduced graphene oxide composite (rGO/NiWO4) electrocatalysts for the oxygen evolution reaction in alkaline medium. The data likely contains measurements of overpotential, Tafel slope, and stability for these materials.

Use Cases

• Compare electrocatalyst performance based on overpotential and Tafel slope values mentioned in the description
• Analyze the effect of reduced graphene oxide incorporation on electrode stability described in the document
• Benchmark new catalyst materials against the reported 50-hour stability test results

Strengths

• Includes specific performance metrics: overpotential of 210 ± 10 mV at 50 mA cm−2 and a Tafel slope of 60 ± 3 mV dec−1 for the composite catalyst.
• Reports a concrete stability duration: over 50 hours of continuous operation for the composite electrode.
• Released under a permissive CC-BY-4.0 license, allowing for reuse and modification.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (190.6 KB), indicating limited scope.
