Phosphorus-doped graphene-wrapped molybdenum disulfide hollow spheres as anode material for lithium-ion batteries

Ionic liquid assisted hydrothermal synthesis of MoS2 double-shell polyhedral cages with enhanced catalytic hydrogenation activities

“…Besides, most studies about hollow materials focused on the electrochemistry performance. 31,32 The inuence of hollow structure on traditional catalytic performance of MoS 2 materials needs to be studied further.…”

Heterogeneous Solid Carbon Source‐Assisted Growth of High‐Quality Graphene via CVD at Low Temperatures

“…The binding energy of the P 2p peak is expected to be 132 eV; however, no such peak was observed at this position ( Figure S1, Supporting Information). [ 17 ] We attributed the absence of P in graphene to the high solubility of P in Cu, even at low temperatures. Unlike carbon, which is insoluble in Cu, phosphorous is soluble in copper and forms stable compounds such as Cu 3 P or CuP 2 .…”

Stabilizing effect of 2-(triphenylphosphoranylidene) succinic anhydride as electrolyte additive on the lithium metal of lithium metal secondary batteries

“…The P 2p XPS spectra of the bare electrolyte showed a single merged peak over the range 134-137 eV correlating to the decomposition of LiPF 6 (Li x PF y : 136.5 eV, Li x PO y F z : 134.5 eV), whereas 3 wt.% TPSA showed two separated peaks located near 136.0 and 132.0 eV [42]. For comparison, pure TPSA powder, which contains P-O (132.9 eV) and P-C (131.5 eV) bonds, was also analyzed by XPS and was found to display a single merged peak near 132.0 eV [43]. The normalized peak intensity corresponding to P 2p, which is summarized in Table 2, shows that the SEI of 3 wt.% TPSA contains a larger portion of chemical decomposition product ascribed to TPSA.…”
