文摘

A photoelectrochemical system was set up with commercial triple-junction solar cells to split water into hydrogen. To minimize the Pt loading and material cost and to maintain a high catalytic activity, a thin Pt layer on a high-surface-area Ni foam was used to catalyze the hydrogen evolution reaction. The solar-to-hydrogen efficiency measured from the hydrogen gas evolved is as high as 9.5 %.
