Single-step synthesis of PtRu/N-doped graphene for methanol electrocatalytic oxidation

Nitrogen-doped graphene guided formation of monodisperse microspheres of LiFePO4 nanoplates as the positive electrode material of lithium-ion batteries

“…LFP/NG shows higher I D /I G value than LFP/G, suggesting that more structural defects have been introduced after N-doping, which is consistent with the previously reported N-doped graphene. 3,29 In comparison to LFP/G, both bands of LFP/NG slightly shift to lower frequencies implying good electronic contact and interaction between LFP and NG. 3,30 In addition, thermogravimetric analysis ( Fig.…”

“…29,32 As displayed in Table 1, the C-C bond was dominant in the C functional groups, which may contribute to the electronic conductivity improvement of the composite materials. 29 The presence of C-N bond in LFP/NG further proves the formation of N-doping nanocarbon in this sample. The O 1s spectrum could be decomposed into four peaks of O-P, O-C, O=C and O-C=O, located respectively at 530.9, 531.5, 532.6 and 533.8 eV (Fig.…”

“…7b could be deconvoluted into five peaks at 284.6, 285.9, 286.5, 287.9 and 289 eV, respectively ascribed to C-C, C-N, C-O, C=O and O-C=O. 29,32 As displayed in Table 1, the C-C bond was dominant in the C functional groups, which may contribute to the electronic conductivity improvement of the composite materials. 29 The presence of C-N bond in LFP/NG further proves the formation of N-doping nanocarbon in this sample.…”

“…7a could be reasonably fitted with three components of pyridine type N (398.3 eV), amino type N (399.4 eV) and graphitic type N (401.1 eV), with the corresponding contents of 27.26%, 36.12% and 36.62%, respectively. 29,32 The high resolution C 1s spectrum in Fig. 7b could be deconvoluted into five peaks at 284.6, 285.9, 286.5, 287.9 and 289 eV, respectively ascribed to C-C, C-N, C-O, C=O and O-C=O.…”

Palladized cells as suspension catalyst and electrochemical catalyst for reductively degrading aromatics contaminants: Roles of Pd size and distribution

“…6b. A typical shape with a semicircle was observed in the high frequency region corresponding to charge transfer resistance of electrode (Xu et al, 2014). It was found that the semicircular diameter of the Pd-cell catalyst from group E was considerably much smaller than those of other groups of Pd-cells, suggesting the faster reaction rate and higher efficiency in charge transport (Zhou et al, 2016a).…”
