11. Pt/CuNWs were synthesized with a diameter of 100 nm and a length of 25−40 μm (Figure 1 a−b). PtNTs (Cu) were synthesized with a wall thickness of 11 nm (as determined by high resolution TEM images), an outer diameter of 100 nm, and a length of 5−20 μm (Figure 1 c−d and Supporting Information, Figure S.1). The CuNWs used in the galvanic displacement had an outer diameter of 100 nm and a length of 40−50 μm (Supporting Information, Figure S.2). Previously synthesized PtNTs (Ag) had a wall thickness of 5 nm, an outer diameter of 60 nm, and a length of 5−20 μm. 9,10 The Pt loading of Pt/CuNWs and PtNTs (Cu) was 18 wt % (total mass, 82 wt % Cu) and 95 wt % (total mass, 5 wt % Cu), respectively. Previously synthesized PtNTs (Ag) were also found to have a Pt content of 97 wt % (total mass, 3 wt % Ag). Pt loadings were determined by energy dispersive X-ray spectroscopy (EDS). 12. SAED patterns of CuNWs matched those previously found by Zeng et al. and con fi rmed the presence of single twinned CuNWs with growth in the [1,−1,0] direction (Supporting Information, Figure S.3). 15,17 High resolution TEM images showed a [1,−1,1] lattice spacing of 0.25 nm (Supporting Information, Figure S.4). SAED patterns of PtNTs also matched the patterns of CuNWs provided by Zeng et al. 1 The PtNTs therefore grew in the [1,−1,0] direction; high resolution TEM images con fi rmed a [1,−1,1] lattice spacing of 0.25 nm. The ability of Pt to maintain the growth directions and lattice spacing of CuNWs was in part attributed to matches in crystal structure and similar atomic size. |

11。合成的Pt / CuNWs直徑為100納米，長度為25-40微米（圖1的a-b）。 PtNTs（Cu）的壁厚（通過高分辨率TEM圖像確定）為11納米，外徑100nm，長度5-20微米（圖1中c-d和支持信息，圖S.1）。電位移所用的CuNWs外徑100nm,長度40-50微米（支持信息，圖S.2）。以前合成PtNTs（Ag）壁厚度為5nm，外徑60nm，長度5-20微米。 9,10 Pt占Pt / CuNWs和PtNTs（銅）分別為18％（重量）（總質(zhì)量，Cu82％）和95重量％（總質(zhì)量，Cu5％）。以前合成PtNTs（銀）發(fā)現(xiàn)具有鉑含量為97％（總重量，3重量％的Ag）。Pt的含量通過能量色散X射線譜（EDS）確定。 12。CuNWs的分區(qū)電子衍射圖案與原先Zeng等的發(fā)現(xiàn)吻合。而且證實了單孿生CuNWs與生長[1，-1,0]方向（支持信息，圖S.3）的存在。 15,17 分辨率透射電子顯微鏡圖像顯示了[1，-1,1]0.25納米的的晶格間距（支持信息，圖S.4）。 PtNTs的分區(qū)電子衍射圖案也與Zeng等的CuNWs圖案相符。 1 PtNTs因此在[1，-1,0]方向生長;高分辨TEM圖像證實了0.25納米的[1，-1,1]晶格間距。鉑保持生長的方向和CuNWs的晶格間距的能力，部分歸因于晶體結(jié)構(gòu)和類似的原子尺寸的匹配。 |
