Preparation of iron doped carbon coated W18O49 and its photoactivity
Journal Title: Carbon - Science and Technology - Year 2008, Vol 1, Issue 1
Abstract
Iron doping to carbon coated W18O49 was carried out through solid-state reaction of WO2.9 with iron acetate at 400oC, followed by carbonization with poly(vinyl alcohol) (PVA) as carbon precursor at 800oC in N2 atmosphere. Photoactivities of these samples were confirmed by phenol photodecomposition in its aqueous solution. They revealed the photoactivity under visible light irradiation. Carbon coated W18O49 with iron exhibited higher photoactivity than it without iron. Addition of 1 % iron and 90/10 mixing ratio (WO2.9/PVA) derived the highest photoactivity to decompose the phenol.
