The XRD, Raman and XPS analysises were used to investigate the crystalline phase and chemical states of Co3S4 nanowires, as shown in Fig. 1. In the XRD patterns of Co3S4 nanowires, the peaks at 31.5°, 38.1°, 50.2° and 55.3° were detected, which were well indexed to (3 1 1), (4 0 0), (5 1 1) and (4 4 0) planes of Co3S4 (JCPDS No. 42-1448), respectively. The two peaks at 44.8°and 52.1°were well matched the (1 1 1) and (2 0 0) planes of Ni foam substrate. No extra peaks were observed, suggesting the high

Three dimensional (3D) Co3S4 nanowires on Ni foam were fabricated by a facile two-step method, and exhibited the electrochemical performances for energy storage and conversation. As the electrode for supercapacitor, Co3S4 nanowires presented the discharge time of 1308.0 s, areal capacitance of 6540 mF cm−2 and long-term stability (∼92% areal capacitiy retained over 4000 cycles). The Co3S4 nanowires/NF//AC asymmetric supercapacitor displayed a potential window of 0–1.6 V. When Co3S4 nanowires used as the electrode for urea electrolysis, they ...
