具有低质量负载的CoS 2纳米锥阵列在3D碳纤维纸上制造的（0.625 mg cm-2）对酸性析氢表现出低起始电位（0.61 mV）和小过电位（0.140 mV）的活性，用于驱动0.100 mA cm-2的电流密度，这归因于一步溶剂热合成，独特的3D纳米结构和电催化剂的固有金属性质。
A CoS2 nanopyramid array with a low mass loading (∼0.625 mg cm−2) fabricated on 3D carbon fiber paper exhibits ultrahigh activity towards acidic hydrogen evolution with a low onset potential (∼61 mV) and a small overpotential (∼140 mV) for driving a current density of ∼100 mA cm−2, ascribed to the one-step solvothermal synthesis, unique 3D nanostructure and intrinsic metallic properties of the electrocatalyst.
