2. Novel two-step vapor-phase synthesis of UV – Vis light active Fe2O3/WO3 nanocomposites for phenol degradationDavide Barreca, Giorgio Carraro, Alberto Gasparotto, Chiara Maccato, Cinzia Sada, Elza Bontempi, Mariangela Brisotto, Olena Pliekhova, Urška Lavrenčič Štangar, 2016, izvirni znanstveni članek Opis: Supported Fe2O3/WO3 nanocomposites were
fabricated by an original vapor phase approach, involving
the chemical vapor deposition (CVD) of Fe2O3 on Ti sheets
and the subsequent radio frequency (RF)-sputtering of WO3.
Particular attention was dedicated to the control of the W/Fe
ratio, in order to tailor the composition of the resulting
materials. The target systems were analyzed by the joint use
of complementary techniques, that is, X-ray diffraction
(XRD), field emission-scanning electron microscopy
(FE-SEM), atomic force microscopy (AFM), energy
dispersive X-ray spectroscopy (EDXS), X-ray photoelectron
spectroscopy (XPS), secondary ion mass spectrometry
(SIMS), and optical absorption spectroscopy. The results
showed the uniform decoration of α-Fe2O3 (hematite)
globular particles by tiny WO3
aggregates, whose content
could be controlled by modulations of the sole sputtering time. The photocatalytic degradation of phenol in the liquid phase
was selected as a test reaction for a preliminary investigation
of the system behavior in wastewater treatment applications.
The system activity under both UVand Vis light illumination
may open doors for further material optimization in view of
real-world end-uses.
