Surface Area and Porosity
Author
Summary, in English
The BET surface area was found to be 10.5 (±0.5), 10.1 (±0.5) and 11.0 (±0.5) m2 g−1 for sample EL10, EL10V1 and EL10V8, respectively. No microporosity was observed for any of the samples. In all cases, a bimodal distribution of porosity was observed, indicating intraparticle macroporosity with radii about 0.1–0.2 and interparticle porosity radii around 10 μm. The TiO2 support is composed of particles with radii of about 1 μm, these forming aggregates of loosely coherent particles (radii 100 μm). Impregnation by the V2O5 compound does not modify appreciably either the surface area or the degree of aggregation.
