[资源] 最近一篇光催化TiO2 NATURE NANOTECHNOLOGY

同样都是做的TiO2光催化，2011年出了一篇黑色TiO2的science，2012年又有nature chemistry的Au-TiO2的光催化。现在又出了一篇关于TiO2 的NATURE NANOTECHNOLOGY。也不知道有没有人发，也不做太多评论了，就让我们欣赏一下学术大家们的学术思路与造诣吧。
Solar conversion to electricity or to fuels based on electron–
hole pair production in semiconductors is a highly evolved
scientific and commercial enterprise1–10. Recently, it has been
posited that charge carriers either directly transferred from
the plasmonic structure to a neighbouring semiconductor
(such as TiO2) or to a photocatalyst, or induced by energy
transfer in a neighbouring medium, could augment photoconversion
processes, potentially leading to an entire new paradigm
in harvesting photons for practical use11–16. The strong
dependence of the wavelength at which the local surface
plasmon can be excited on the nanostructure makes it possible,
in principle, to design plasmonic devices that can harvest
photons over the entire solar spectrum and beyond. So far,
however, most such systems show rather small photocatalytic
activity in the visible as compared with the ultraviolet17–26.
Here, we report an efficient, autonomous solar water-splitting
device based on a gold nanorod array in which essentially all
charge carriers involved in the oxidation and reduction
steps arise from the hot electrons resulting from the
excitation of surface plasmons in the nanostructured gold.
Each nanorod functions without external wiring, producing
531013 H2 molecules per cm2 per s under 1 sun illumination
(AM 1.5 and 100 mWcm22), with unprecedented long-term
operational stability.
