Abstract

Hydrogen gas (H₂) was produced by gamma-irradiation of pure water in the presence of various TiO₂ catalysts. Most catalysts used in this work largely enhanced the radiolytic decomposition of water and subsequent production of H₂. The different activity of catalysts was characterized by X-ray diffraction (XRD) patterns and by electron paramagnetic resonance (EPR) spectra. The addition of methanol as a sacrificing agent further increased the H₂ production by scavenging hydroxyl radicals and the scavenging activity was directly identified using an EPR/spin-trapping technique. Among the catalysts studied, nanosized TiO₂ (nTiO ₂) showed an excellent activity in the production of H₂. Furthermore, the addition of EDTA instead of methanol largely increased the H₂ production. This is quite promising since waste compounds such as EDTA can be removed with concomitant H₂ production.
