Figure 3. H2 production over different catalysts via (A) thermocatalysis (100 °C); (B) photocatalysis; (C) thermo-photocatalysis (100 °C); (D) thermo-photocatalytic H2 production over 3DOM CaTiO3-Au prepared by different volumes of HAuCl4 (actual loading of Au is labeled); (E) thermo-photocatalytic H2 production over 3DOM CaTiO3-Au prepared by 1.5 mL of HAuCl4 under different reaction temperatures; and (F) long-time cycling test.
