摘要

Highly ordered mesoporous carbon (MC) has been synthesized from sucrose, a non-toxic and cost- effective source of carbon. X-ray diffraction, N2 adsorptionesorption isotherm and transmissionelectron micrograph (TEM) were used to characterize the MC. The XRD patterns show the formationof highly ordered mesoporous structures of SBA15 and mesoporous carbon. The N2 adsorption- desorption isotherms suggest that the MC exhibits a narrow pore-size distribution with high surface2 area of 1559 m /g. The potential application of MC as a novel electrode material was investigatedusing cyclic voltammetry for riboflavin (vitamin B2) and dopamine. MC-modified glassy carbonelectrode (MC/GC) shows increase in peak current compared to GC electrode in potassiumferricyanide which clearly suggest that MC/GC possesses larger electrode area (1.8 fold) comparedwith bare GC electrode. The electrocatalytic behavior of MC/GC was investigated towards theoxidation of riboflavin (vitamin B2) and dopamine using cyclic voltammetry which show largeroxidation current compared to unmodified electrode and thus MC/GC may have the potential to beused as a chemically modified electrode.
