Abstract

Hydrogen production from water using solar light energy is a significant contribution to green renewable energy economy. Separation of water splitting products is essential for this and approached by creating membrane photocatalytic system (MPS) without macroscopic metallic electrodes. The MPS has a layered structure Pt/chemically loaded TiO₂/filtration loaded TiO₂/porous polymer membrane/support. Influence of MPS preparation conditions on its TiO₂ content, permeability, diffuse reflectance spectra, mechanical stability, Pt loading and membrane morphology was investigated. Chemical bath deposition of TiO₂ followed by aging was found to be essential for mechanical stability and high activity in hydrogen production. Loading TiO₂ by filtration alone is ineffective for achieving low permeability. The detected products of ethanol dehydrogenation in gas phase were H₂, CO₂, CH₄ and C ₂H₆ and in liquid phase CH₃COOH and CH ₃CHO. Optimum mass of TiO₂ and photodeposited Pt were found for high rate of H₂ generation. The highest quantum efficiency of H₂ production was 13%.
