Multiwalled Carbon Nanotube-TiO₂ Nanocomposite for Visible-Light-Induced Photocatalytic Hydrogen Evolution

Figure 4

H₂ evolution efficiency over MWCNT, TiO₂, and various photocatalysts containing MWCNT and TiO₂ under visible-light (λ > 420 nm) and full spectra irradiation. Conditions: 1 wt% Pt-loading; 15 vol % TEOA solution (100 mL); light source, 300 W Xe-lamp. MWCNTs + TiO₂: MWCNTs and TiO₂ nanoparticles were simply mixed together.
