Sponge-like NiN/NC was prepared through a facile approach and was examined as a catalyst for the oxygen evolution reaction (OER). This material can efficiently catalyze water oxidation to reach a current density of 10 mA cm with a small overpotential of 310 mV in 1.0 M KOH aqueous solution. The high efficiency can be attributed to the good electronic conductivity, large specific surface area and fast mass diffusion ability of NiN/NC.
通过一种简便的方法制备了海绵状的NiN/NC,并将其作为析氧反应(OER)的催化剂进行了研究。这种材料能够在1.0 M KOH水溶液中高效催化水氧化,以310 mV的小过电位达到10 mA cm²的电流密度。这种高效率可归因于NiN/NC良好的电子导电性、大比表面积和快速的质量扩散能力。
