    pubs.acs.org/doi/10.1021/acscatal.6b01878 A chemical synthesis for the cobalt pertelluride mineral mattagamite is reported. Synthetic nanocrystalline mattagamite was investigated for electrochemical water oxidation and showed catalytic activity. Electrochemical water oxidation occurred at an overpotential of 380 mV at 10 mA/cm−2 with a Tafel slope of 58 mV/decade and with a Faradaic efficiency of 96% and turnover frequency of 0.021 ...
  • mp-9945: CoTe2 (orthorhombic, Pnnm, 58)

    materialsproject.org/materials/mp-9945 CoTe2 is Marcasite structured and crystallizes in the orthorhombic Pnnm space group. The structure is three-dimensional. Co4+ is bonded to six equivalent Te2- atoms to form a mixture of edge and corner-sharing CoTe6 octahedra. The corner-sharing octahedral tilt angles are 56°. There are two shorter (2.58 Å) and four longer (2.59 Å) Co–Te bond lengths.
