To enhance H-2 yields from the photocatalytic splitting of seawater, better photocatalysts such as nanostructured TiO2 promoted with NiO (2.5%) and CuO (2.5%) have been studied in the present work. The accumulated H-2 yielded from the photocatalytic splitting of seawater containing oxalic acid (50 mM) as the sacrificial reagents on CuO/nano-TiO2 is 8.53 mu mol/g(cat) after the 5 h radiation. On the NiO/nano-TiO2 photocatalyst, the H-2 yield is relatively low (i.e., 1.46 mu mol/g(cat)). Note that the hole scavenging with chlorides in seawater may be associated with the less H-2 yielded from the seawater photocatalysis (on CuO/nano-TiO2) if compared with that from water (42.4 mu mol/g(cat)).
