摘要:
The highly active electrodes for the oxygen evolution reaction (OER) are vital for boosting the overall efficiency of electrocatalytic water splitting to produce hydrogen fuel. Here we demonstrate a facile in-situ sulfurization strategy to construct an additive-free electrode with low-crystalline Co9S8-Ni3S2 nanohybrid under the joint effects of fast sulfurization and lattice-mismatched growth. The Co9S8-Ni3S2 nanohybrid exhibits semi-spherical architecture constructed with interconnected nanoflakes, and contains mesopores with an average pore size of 12.66 nm. The crystalline degrees of Ni3S2...
