{2-})\). For covellite structure of CuS, the cation: anion ratio remains 1:1. Based upon the total cation site of 1, the above molecular formula can be re-written as\((C{u}_{0.660}^{+}C{u}_{0.199}^{2+}{{\rm{Ni}}}_{0.032}^{2+}{S}_{0.109}^{6+})({O}_{0.414}^{...
Co3O4 has been widely studied for its high theoretical specific capacity. However, its low electronic conductivity and large volume expansion during cycles
X-ray spectroscopy elemental mapping in TEM (Figures 1c and e). With a further increase in added Hf4+, the structure of the Mn/Hf-IR825 NMOPs gradually changed from a core-shell structure into a co-doped structure (Figures 1d and f). Similar to the Mn-IR825 NMOPs reported in our...
