2026-08-24 Cu–Nd Bimetallic Hexaaluminates for Enhanced N2O Decomposition with High-Temperature Stability doi:10.57760/sciencedb.01016 en The dataset includes synthesis, characterization, and catalytic performance records for monometallic and bimetallic hexaaluminate catalysts. 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. Raw XRD files (.raw), TPR/TPD profiles (.txt), and microscopy images (.tiff) are included, readable with common crystallography software (e.g., MDI Jade).
