摘要：The porous Cu7.2S4 sub-microspheres were synthesized by ion exchange reaction using Cu2O as a precursor. The morphology and structure of the obtained samples were characterized by XRD, SEM, and TEM analysis in detail and the formation mechanism was studied. The pseudo-capacitive properties were evaluated by CV and galvanostatic charge-discharge tests in 6 M KOH solution. The as-prepared porous Cu7.2S4 sub-microspheres electrode has a specific capacitance of 491.5 F g(-1) at 1 A g(-1) and exhibits good electrochemical performance as an electrode material for supercapacitors.
