论文摘要
报道了增加金属玻璃（MGS）在氢进化反应（HER）中的电催化活性的有效方法。该方法采用高贵的金属杂交策略来设计基于纳米孔结构的MGS的碱性催化剂。多孔结构提供了丰富的活性位点，并向电解质暴露了大的特定表面积，从而有效地改善了她的催化剂的活性。 AU元件的掺杂可以产生电子缺陷，调整电子结构，改变电子相互作用，引入晶格失真，调节混合熵并改善催化剂的电催化性能。所有这些特性使NP-AlmnynicoAu催化剂成为碱性HE的潜在电极。值得注意的是，我们发现高混合熵可以增强她的表现。目前的工作可能会导致一种新的方法，以进一步开发环保的无定形电催化剂，并在碱性溶液中为她提供高效率和出色的稳定性。
An effective method for increasing the electrocatalytic activity of metallic glasses (MGs) in hydrogen evolution reaction (HER) is reported. This method applies a noble metal hybridization strategy to design a highly reactive catalyst for alkaline HER based on MGs with a nano-porous structure. The porous structure provides an abundance of active sites and exposes a large specific surface area to the electrolyte, thus effectively improving the activity of the HER catalysts. The doping of Au element can create electronic defects, adjust the electronic structure, change the electronic interaction, introduce lattice distortion, regulate mixing entropy, and improve the electrocatalytic performance of the catalyst. All these properties make np-AlMnYNiCoAu catalyst a potential electrode for alkaline HER. Significantly, we find that the high mixing entropy can enhance the HER performances. The present work could lead to a new approach to further develop environmentally friendly amorphous electrocatalyst with high efficiency and excellent stability for HER in alkaline solution.
