Engineering Photocatalytic Cements: Understanding TiO2 Surface Chemistry to Control and Modulate Photocatalytic Performances
The present work addresses the aggregation/dispersion properties of two commercial titanias for application as photocatalysts in concrete technology. A microsized m-TiO2 (average particle size 153.7 ± 48.1 nm) and a nanosized n-TiO2 (average particle size 18.4 ± 5.0 nm) have been tested in different ionic media (Na+, K+, Ca2+, Cl−, SO42−, synthetic cement pore solution) at different pHs and in real cement paste specimens. Results highlighted that ion–ion correlations play a fundamental role in TiO2 particles aggregation in the cement environment. A particle aggregation model derived from TiO2 surface chemistry is proposed here and used to justify such aggregation phenomena in real cement pa…
O-Doped Nanographenes: A Pyrano/Pyrylium Route Towards Semiconducting Cationic Mixed-Valence Complexes
Herein we report an efficient synthesis to prepare O‐doped nanographenes, which derive from the longitudinally and latitudinally p‐extension of pyrene. The derivatives are highly fluorescent and feature low‐oxidation potentials. Exploiting electrooxidation, crystals of cationic mixed valence (MV) complexes were grown in which the organic salts organize into face‐to‐face p‐ p stacks, a favorable solid‐state arrangement for organic electronics. Variable‐temperature EPR measurements and relaxation studies suggest a strong electron delocalization along the longitudinal axis of the columnar p‐stacking architectures. Electric measurements of single crystals of the MV salts exhibited a semiconduct…
