做核殼結(jié)構(gòu)中的銀核怎么去除?
|
| 現(xiàn)在本人做核殼結(jié)構(gòu),用的是銀核,外面包一層SIO2,然后在SIO2上包了其它的性能材料后把SIO2腐蝕掉后做成中空的核殼結(jié)構(gòu),而現(xiàn)在需要做一組對比實驗,就是沒有銀核的情況下與有銀核情況下的性能比較,不知道有什么方法可以把銀核除去呢? |

^_^,這篇文章太新了,還沒有正式出版。你下來看看吧。 Ultrathin Gold Nanoframes through Surfactant-Free Templating of Faceted Pentagonal Silver Nanoparticles, http://pubs.acs.org/doi/pdf/10.1021/ja111642d Ultrathin gold nanoframes (up to 1.6 nm) were prepared via templating upon well-defined faceted silver morphologies. Starting with silver decahedra, small quantities of gold (1–10 mol % relative to the amount of silver) were selectively deposited on the nanoparticle edges under optimized reducing conditions. Silver dissolution in hydrogen peroxide yielded well-defined gold frames that retained their structural integrity in the ultrathin nanowire regime below 2 nm. The frame formation protocol was also successfully applied to other silver nanoparticle shapes featuring pentagonal twinning and (111) facets (e.g., pentagonal faceted rods and icosahedra). The demonstrated approach can be applied in the controlled preparation of ultrathin metal nanowires complementary to lithography and in the production of ultrafine noble-metal nanostructures for catalytic applications. |
