Abstract

The present investigation is development of the TiOnanotubes concept of preparation of and their composite with fine dispersion of copper. The inventions also relates to identify a method for optimum amount of photocatalyst required for efficient and maximum hydrogen production reported than earlier (H=99,823 μmol·h·gcatalyst) from glycerol-water mixtures under solar light irradiation. A method is disclosed to produce CuO/TiOnanotubes with high sustainability and recyclable activity for hydrogen production.
