[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.

值得下载阅读。我实习是做光催化的,可惜都是给老板打杂处理数据,半年下来实验没有什么进展。现在做UV消毒和高级氧化处理饮用水,不知道光催化是否也可以应用到水处理,楼主有这方面信息吗?

当然可以的,你在网上可以找到好多光催化进行水处理的文章
