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直径为100纳米，长度为25-40微米（图1的a-b）。 PtNTs（Cu）的壁厚（通过高分辨率TEM图像确定）为11纳米，外径100nm，长度5-20微米（图1中c-d和支持信息，图S.1）。电位移所用的CuNWs外径100nm,长度40-50微米（支持信息，图S.2）。以前合成PtNTs（Ag）壁厚度为5nm，外径60nm，长度5-20微米。 9,10 Pt占Pt / CuNWs和PtNTs（铜）分别为18％（重量）（总质量，Cu82％）和95重量％（总质量，Cu5％）。以前合成PtNTs（银）发现具有铂含量为97％（总重量，3重量％的Ag）。Pt的含量通过能量色散X射线谱（EDS）确定。 12。CuNWs的分区电子衍射图案与原先Zeng等的发现吻合。而且证实了单孪生CuNWs与生长[1，-1,0]方向（支持信息，图S.3）的存在。 15,17 分辨率透射电子显微镜图像显示了[1，-1,1]0.25纳米的的晶格间距（支持信息，图S.4）。 PtNTs的分区电子衍射图案也与Zeng等的CuNWs图案相符。 1 PtNTs因此在[1，-1,0]方向生长;高分辨TEM图像证实了0.25纳米的[1，-1,1]晶格间距。铂保持生长的方向和CuNWs的晶格间距的能力，部分归因于晶体结构和类似的原子尺寸的匹配。 |
