Abstract
Official abstract text for this publication.
The present investigation is development of the TiO 2 nanotubes 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 2 =99,823 μmol·h −1 ·g −1 catalyst) from glycerol-water mixtures under solar light irradiation. A method is disclosed to produce CuO/TiO 2 nanotubes with high sustainability and recyclable activity for hydrogen production.
First claim
Opening claim text (preview).
What is claimed is: 1. A process for H 2 production from glycerol-water mixture using a CuO—TiO 2 nanocomposite photocatalyst comprising TiO 2 nanotubes in the range of 98-99.9 wt % and CuO in the range of 0.1 to 2 wt %, wherein the said process comprises stirring the CuO—TiO 2 nanocomposite photocatalyst with a glycerol-water mixture (3 to 7 vol. %) for a period ranging between 0.5 to 2 h under dark conditions at a temperature ranging between 28-34° C. followed by evacuation and purged with N 2 gas subsequently stirring the solution under solar light for a period ranging between 1 to 4 h to obtain H 2 gas. 2. The process as claimed in claim 1 , wherein H 2 production rate is in the range of 82,746 to 99,823 μmol·h −1 ·g −1 catalyst.
