Cobalt-doped MoS2 nanosheets were prepared via a facile hydrothermal method, exhibiting bifunctional activities of hydrogen and oxygen evolution reactions in both acidic and alkaline media. Cobalt doping not only improves the conductivity, decreasing the hydrogen adsorption free energy of MoS2 for HER, but also contributes catalytic active sites for OER.
通过简便的水热法制备了钴掺杂的 MoS2 纳米片，在酸性和碱性介质中均表现出析氢反应（HER）和析氧反应（OER）的双功能活性。钴掺杂不仅提高了导电性，降低了 HER 中 MoS2 的氢吸附自由能，而且还为 OER 提供了催化活性位点。
