| 英文摘要 |
Photonic nanostructures hold great promise in promoting light harvesting. Here
we report the first design and construction of a three-dimensional (3D) hexagonal
nanocone array of fluorine-doped tin oxide (FTO) on glass as an excellent electrode
for photoelectrochemical (PEC) water splitting. The PEC current density with
suitably deposited Ti-doped hematite at 1.23 V vs. the reversible hydrogen electrode
(RHE) was increased by 86% to 2.24 +/- 0.02 mA cm(-2) compared to that with the
planar counterpart, mainly ascribable to the special light harvesting effect and the
electrode surface area provided by 3D FTO. Upon the embedment of a gold layer to
concentrate the incident light onto the hematite layer and the deposition of the
Co-Pi catalyst with a modified procedure, the photocurrent experienced a large
cathodic shift of onset potential by 360 mV and soared to a high value of 3.39 +/-
0.01 mA cm(-2) (at 1.23 V), yielding a power conversion efficiency of 0.70% at a
potential as low as 0.88 V vs. RHE. |
