Synergy of the Combination of Titanate Nanotubes with Titania Nanoparticles for the Photocatalytic Hydrogen Generation from Water-Methanol Mixture Using Simulated Sunlight

Figure 4

Photocatalytic hydrogen production from water-methanol (3 : 1) mixtures of selected samples as photocatalysts under simulated sunlight irradiation. Reaction conditions are water-methanol (3 : 1) mixtures 25 mL and catalyst concentration 1.0 g × L−1. Refer to Table 1 for sample codes and a complete set of hydrogen production values. (a) Samples containing titanate nanotubes and Millennium PC500 TiO2 particles. (b) Samples containing titanate nanotubes and Evonik P25 TiO2 particles.
