此前,我们已经推出了XRD,SEM,TEM,XPS等相关实验结果的表述方式,大家可以进入科研资料--论文写作专栏进行查看。 1. 如何详细地描述FT-IR的实验结果? FT-IR analysis was further carried out to verify the conversion of PbO in the reaction process. As shown inFig. 1B, after reacting with HCHO, several...
我们对催化剂做了 TEM、XPS、ICP、XRD 等表征,详细信息请参见文章。TEM 证明了催化剂是核壳结构,其中核为 Pt 富集而成,壳为 Ir 富集而成,并且壳层的厚度接近于 1~2 个原子层。同时,我们在合成过程中对中间产物进行了组分和电化学分析,发现在反应中期,反应中间产物的组成接近纯铂,Ir 很少还原到纳米颗粒上,...
The O 1 s XPS spectra (Supplementary Fig. 32 and Supplementary Table 7) revealed the changes in the contribution of lattice oxygen (OM-O), hydroxyl groups (OM-OH), and adsorbed water (OM-H2O) in both (RuIr)O2/C and RuO2@IrO2/C after OER. For (RuIr)O2/C, the lattice oxygen...
