报道了碲化钴矿物mattagamite的化学合成方法。合成的纳米晶mattagamite用于电化学水氧化，并显示出催化活性。电化学水氧化发生在10 mA/cm−2下380 mV的过电位下，塔菲尔斜率为58 mV/decade，法拉第效率为96%，在0.5 V下转换频率为0.021 s-1。
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 s–1 at 0.5 V.
