چکیده
|
In this study, we report a facile hydrothermal method for the synthesis gns/vs2 nanosheets in the presence of cetyltrimethylammonium bromide (ctab). hexamethylenetetramine (hmta) or urea is used as the alkali agent to produce mn-co layered double hydroxide (ldh) nanoparticles. then, mnco2o4 arrays on gns/vs2 nanosheets to form gns/vs2/mnco2o4 three component hybrid as an active material for suitable-performance supercapacitor electrode. this unique structural exhibiting specific capacitances of 414.76 f g−1 at current density of 1 a g−1 with long cycle stability (nearly 88.52% specific capacitance retains after successive 1000 charge/discharge cycle).
