Addition of Fe to PtPd nanoparticles on γ-alumina is known to increase catalytic activity. This is shown to stem from increased Pt-Pd coordination during thermal aging which induces microstrain. X-ray absorption spectroscopy analysis reveals that th

Publikováno v: Nanoscale. 12(4)

Titania nanocrystals are used in numerous applications but specific polymorphs (anatase, rutile, brookite) are typically required in specific applications making synthesis control over the crystal phase essential. Supercritical continuous flow reacto
