摘要: Abstract The carbon supported AuNi electrocatalyst (AuNi/C) for electrochemical oxidation of borohydride is prepared in water-in-oil microemulsion water/AOT/n-heptane. effects the molar ratios water to AOT (Rω) on particle size and catalytic performance are systemically investigated. It has been found that when Rω less than 10, increases with increase value, decreased after Rω > 10 due two-phase separation microemulsion. morphology structure as-prepared AuNi/C electrocatalysts examined by transmission electron microscopy (TEM) X-ray diffractometer (XRD). confirmed all nanoparticles spherical average diameters range 3–9 nm uniformly distributed surfaces carbon. electrooxidation behaviors BH 4 − anodic have results show activity apparently improved smaller can get a higher activity.
