Abstract

Photocatalytic remote oxidation was examined under visible light by using WO₃-based photocatalysts: WO₃, WO₃ modified with Pt nanoparticles (Pt-WO₃), and WO₃ modified with Cu(II) ions (Cu(II)-WO₃). Alkyl chains on a glass plate separated from the photocatalyst by 7.5 μm thick air were removed in 40 min under visible light (≥420 nm, ∼100 mW cm^-2). Among the photocatalysts examined, Pt-WO₃ exhibits the highest remote oxidation activity. Its activity is higher than that of TiO₂ modified with Pt nanoparticles in the wavelength range 360-460 nm. It is likely that Pt-WO ₃ emits ^·OH under visible light, which diffuses in air and attacks alkyl chains, whereas the major path of the remote oxidation induced by UV light involves emission of H₂O₂ and its photocleavage into ^·OH. Remote storage of oxidative energy in Ni(OH)₂ is also possible by using visible light-irradiated Pt-WO ₃.
