Equivalent spherical diameter (d eq) analysis of separated pore labels from PXCT. Volume renderings of “pores” (8‐bit color code) and “material” (gray) labels for a) Ni/Al2O3‐dr, b) Ni/Al2O3‐calc, d) Al2O3‐dr, and e) Al2O3‐calc. Porosity (ϵ) depending on d eq and Gaussian fit for c) Ni/Al2O3 (d eq binning of 200 nm, number of analyzed pores: Ni/Al2O3‐dr 971 and Ni/Al2O3‐calc 880) and f) Al2O3 (d eq binning of 100 nm, number of analyzed pores: Al2O3‐dr 217 and Al2O3‐calc 265).
