1. A process for H2 production from glycerol-water mixture using a CuO—

  • TiO2 nanocomposite photocatalyst comprising TiO2 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—

    TiO2 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 N2 gas subsequently stirring the solution under solar light for a period ranging between 1 to 4 h to obtain H2 gas.
