Iron (Fe)-doped porous cobalt phosphide polyhedrons are designed and synthesized as an efficient bifunctional electrocatalyst for both hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). The synthesis strategy involves one-step route for doping foreign metallic element and forming porous cobalt phosphide polyhedrons. With varying doping levels of Fe, the optimized Fe-doped porous cobalt phosphide polyhedron exhibits significantly enhanced HER and OER performances, including low onset overpotentials, large current densities, as well as small Tafel slopes and good electrochemical stability during HER and OER.
铁(Fe)掺杂多孔钴磷多面体被设计并合成作为高效双功能电催化剂用于析氢反应(HER)和析氧反应(OER)。该合成策略涉及一步法掺杂外来金属元素和形成多孔钴磷多面体。通过改变 Fe 的掺杂水平,优化后的 Fe 掺杂多孔钴磷多面体表现出显著增强的 HER 和 OER 性能,包括低起始过电位、大电流密度以及小的 Tafel 斜率和良好的 HER 和 OER 电化学稳定性。
