The structures on the CNTs had been analyzed by Raman spectra, as shown in Figure 3b. The 3b. The Raman spectrum of pristine CNTs had been composed of two powerful peaks at 1335 cmRaman spectrum of pristine CNTs had been composed of two powerful peaks at 1335 cm-1 and 1 and 1572 cm-1, corresponding towards the D and G bands, respectively. The D band constitutes 1572 cm-1 , corresponding towards the D and G bands, respectively. The D band constitutes a a disordered induction characteristic, which can be derived from the vibration of C atoms with disordered induction characteristic, that is derived in the vibration of C atoms with dangling bonds, although the G band is derived in the tangential shear mode in C atoms, dangling bonds, although the G band is derived in the tangential shear mode in C atoms, which corresponds towards the tensile mode in the graphite plane [33,34]. The decrease intensity which corresponds towards the tensile mode within the graphite plane [33,34]. The decrease intensity of D/G band intensity ratio (ID/IG) reflects the greater degree of graphitization; the ratio of of D/G band intensity ratio (ID /IG ) reflects the greater degree of graphitization; the ratio the intensities (ID/IG) was 1.06 for the pristine CNTs and 1.32 for the SnO2/CNT NNs, which with the intensities (ID /IG ) was 1.06 for the pristine CNTs and 1.32 for the SnO2 /CNT NNs, recommended that there was a particular degree of harm to the CNTs structure in the course of action which suggested that there was a certain degree of harm to the CNTs structure inside the of preparing SnO2/CNT NNs by the DC arc-discharge plasma, which is constant with course of action of preparing SnO2 /CNT NNs by the DC arc-discharge plasma, that is constant our prior researches [31]. The defects around the CNTs wallswalls lead to many cavities and with our preceding researches [31]. The defects on the CNTs may may trigger a lot of cavities alleyways within the graphite layers, which is beneficial to enhancing the the anchoring effect and alleyways inside the graphite layers, that is effective to enhancing anchoring effect of SnO2 nanoparticles and and CNTs, also delivers moremore reactionfor Lifor Li . Apart from, of SnO2 nanoparticles CNTs, and and also gives reaction websites web pages . Apart from, CNTs nevertheless have ahave a higher degree of graphitization andretainretainelectrical conductivity. CNTs nevertheless higher degree of graphitization and therefore hence high higher electrical conductivity.Figure 3.

NNs composites. Figure 4a shows the XPS survey spectra ofof SnO2/CNT NNs composites, 4a shows the XPS survey spectra SnO2 /CNT NNs composites, it could be clearly seen that the SnO2 /CNT NNs composites developed peaks corresponding to it may be clearly seen that the SnO2/CNT NNs composites developed peaks corresponding O 1s, C C Sn 3d as at the same time as Sn 3p, indicating the presence in the sample besides CNTs to O 1s, 1s,1s, Sn 3d properly as Sn 3p, indicating the presence of Snof Sn inside the sample in addition to and SnO2 this this really is as a consequence of the fact that a modest volume of Sn not oxidized in the course of the CNTs and ,SnO2,is resulting from the truth that a modest amount of Sn Fmoc-Gly-Gly-OH site waswas not oxidized through preparing course of action by by plas.
