Integrated Ni-P-S nanosheets array as superior electrocatalysts for hydrogen generation

摘要: Searching for efficient and robust non-noble electrocatalysts hydrogen generation is extremely desirable future green energy systems. Here, we present the synthesis of integrated Ni-P-S nanosheets array including Ni2P NiS on nickel foam by a simple simultaneous phosphorization sulfurization strategy. The resultant sample with optimal composition exhibits superior electrocatalytic performance evolution reaction (HER) in wide pH range. In alkaline media, it can generate current densities 10, 20 100 mA cm−2 at low overpotentials only −101.9, −142.0 −207.8 mV durability. It still high activities even acid or neutral media. Such performances be mainly attributed to synergistic enhancement hybrid integration microstructure. kind catalyst gives new insight achieving generation.
