dc.description.abstract | Direct growth of self-supported one-dimensional (1D) nanorod arrays on conducting substrates is highly attractive for electrocatalysis, due to their unique shape, size, and length. In this work, a facile and simple two-step method was employed to synthesize 1D-CoSe2 nanoarrays on titanium (Ti) foil via a wet chemical ion-exchange approach. The as-synthesized 1D-CoSe2 nanoarrays were directly used as electrode materials for hydrogen evolution reaction and supercapacitors. As an electrocatalyst, the optimized 1D-CoSe2(t(ex)-48 h) nanoarray exhibits excellent hydrogen evolution properties with a small Tafel slope of 78 mV dec(-1), low overpotentials of 41 mV@1 mA cm(-2) and 216 mV@10 mA cm(-2), and extended robust performance for 25 h. Moreover, for a symmetric device, it delivers a maximum specific capacitance of 152 F g(-1) at 0.5 A g(-1) and a better energy density of 21.1 W h kg(-1) at a power density of 0.5 kW kg-1. Also, the symmetric device capacity retention behavior achieves similar to 96.8% of the initial result after 5000 cycles, revealing the good stability of the electrode. Our findings offer a new way to further the development of high-performance energy devices. | - |
