We report the electroanalytical detection of n‐butylamine at a nickel/carbon nanotube (Ni/CNT) composite. Scanning Electron Microscopy (SEM) characterisation of the composite demonstrated that it consisted of bulk nickel particles ca. 2 μm in diameter entangled in CNT bundles. The spontaneous formation of Ni(OH)2 was optimised, and comparison with a 3 mm nickel electrode showed that ca. 4 μg of the...
Gold nanoparticles were deposited electrolessly on multiwalled carbon nanotubes (CNTs) via in situ reduction of HAuCl 4 by NaBH 4 . The resulting gold covered nanotubes were immobilised onto the surface of a glassy carbon electrode via evaporation of a suspension in chloroform. Anodic stripping voltammetry was performed with the modified electrode in As(III) solutions. A limit of detection...
