在开发低成本和高效的水裂解制氢系统中，一个富有成效的范例是寻找用于析氢反应（HER）的高活性非贵金属催化剂。在这里，纳米结构的非晶硼化镍（Ni-B）合金的电催化HER活性进行了研究。无定形Ni−B在宽pH范围内表现出优异的催化效率和HER的长期稳定性，这实际上与Pt的性能相当。这种高催化活性是由于Ni−B的无定形结构和中等电子结构。Ni-B催化剂通过化学镀技术容易地获得，并且我们可以在期望的基底上获得负载型Ni-B催化剂。考虑到低成本、丰度、耐腐蚀性、高效率和易于制造，非晶Ni−B是用于水裂解的贵金属析氢催化剂的最佳替代品之一。
A fruitful paradigm in the development of low‐cost and efficient water splitting systems for hydrogen generation is to search the highly active non‐noble catalysts towards hydrogen evolution reaction (HER). Here, the electrocatalytic HER activity of nanostructured amorphous nickel boride (Ni−B) alloy has been investigated. Amorphous Ni−B has exhibited excellent catalytic efficiency and long‐term stability for HER over a broad pH range, which is actually comparable to the performance of Pt. This high catalytic activity is due to the amorphous structure and the moderate electron structure of Ni−B. The Ni−B catalyst is easily obtained via electroless plating technique and we could get a supported Ni−B catalyst on desired substrates. Given the low cost, abundance, corrosion resistance, high efficiency and ease of fabrication, amorphous Ni−B is among the best alternatives to noble metal hydrogen evolution catalysts for water splitting.
