a Cyclic voltammtric curves of the Ni6/AB composites, Ni6(SC12H25)12, and AB in 0.1 KOH with the scan rate of 50 mV/s. b Cyclic voltametric curves of the Ni6/AB composites in 0.1 M KOH without or with the presence of 5 mM glucose with the scan rate of 50 mV/s. c Linear sweep voltametric curves of the Ni6/AB composites in 0.1 M KOH without or with the presence of 5 mM glucose with the scan rate of 10 mV/s. d Linear sweep voltametric curves of the Ni6/AB composites in 0.1 M KOH with the presence of 5 mM glucose under Ar or O2 atmosphere with the scan rate of 10 mV/s
