Cu–Nd Bimetallic Hexaaluminates for Enhanced N2O Decomposition with High-Temperature Stability

Materials were prepared by co‑precipitation with controlled pH, aging, and calcination up to 1200 °C. Characterization employed XRD, N₂ physisorption, H₂‑TPR, and O₂‑TPD; activity was tested in a fixed‑bed reactor with online GC under varying N₂O concentrations, O₂ levels, and space velocities.

Processed data are compiled in an Excel workbook with separate sheets for raw GC areas, calculated conversions (T₁₀/T₅₀/T₁₀₀), and textural properties (BET surface area, pore volume), with units explicitly given. Each reported value is the average of three independent runs; standard deviations and instrumental uncertainty (±1.5% relative) are provided. No missing data are present.
