Graphical Abstract
  • precursors. The thermal gravimetric analysis (TGA) results (see Supporting Information File 1, Figure S2a) show that the IMO:G are 0.82, 1.34 and 2.57 for samples prepared with MnSO4 molar concentrations of 0.15, 0.3 and 0.6 M, respectively. For Mn2O3/graphene samples with higher IMO:G values, the shape of
  • diffraction peaks using Scherrer’s equation. This grain size is much smaller than that of Mn2O3, which is possibly due to a recrystallization process. No impurity phase is detectable using XRD. After the lithiation process, the TGA results (see Supporting Information File 1, Figure S2b) indicate that the

  • thermogravimetric analysis (TGA) [40]. The subsequent ARGET ATRP was carried out by using ascorbic acid (AA) as the reducing agent and anisole as the solvent. Ascorbic acid is insoluble in anisole, hence, the reduction of the Cu(II) complex takes place at the surface of solid ascorbic acid. The slow reaction rate

Thus, there is a phase transformation from h-MoO3 to α-MoO3 at 400 °C, which is inferred from TGA/DTA studies [14][16]. With an increase in temperature, the
