- Summary:The ternaryalloyedCo(SxSe1x)2 nanowires (NWs)supportedbycarbon fiber paper(CFP)have
been successfullysynthesized.ByadjustingthecomponentsoftheNWs,itisfoundthattheCo
(S0.73Se0.27)2 NWs onCFPexhibitthehighestelectrocatalyticactivitytowardshydrogen
evolution reaction(HER).Todrivethecurrentdensityof100mVcm2, theCo(S0.73Se0.27)2
