摘要
Fe2O3-TiO2 nanocomposites on activated carbon fibers (ACFs) have been fabricated by a two-step plasma assisted route, involving the plasma enhanced-chemical vapor deposition (PE-CVD) of iron oxide followed by radio frequency (RF) titanium sputtering for different process durations. A multi-technique characterization of the developed systems has been performed by means of X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), field emission-scanning electron microscopy (FE-SEM), scanning transmission electron microscopy (STEM), and energy dispersive X-ray spectroscopy (EDXS). The adopted approach enabled the successful preparation of high purity composite nanomaterials, with high surface area and characterized by the co-presence of Fe2O3 and TiO2 in tailored amounts. The homogeneous coverage of ACFs by Fe2O3-TiO2, along with the optimal deposit adhesion to the support, candidate the present Fe2O3-TiO2@ACF nanocomposites as attractive systems for photocatalytic applications.
