Determination of hydrogen sulfide in gasoline by Au nanoclusters modified glassy carbon electrode

摘要: Abstract A promising hydrogen sulfide (H2S) sensor was prepared by electrodeposition of Au nanoclusters on glassy carbon electrode (GCE) and the surface structure characterized SEM EDAX. These flower-like form nanoclusters, which were made up highly dense clustering nanorods with an average diameter 20 nm length to 80 nm, had size about 600 nm uniformly distributed GCE surface. The electrocatalytic oxidation H2S in gasoline performed this modified electrode, a satisfactory liner response range 1–80 ppm detection limit 0.45 ppm (s/n = 3). This sensitive, selective stable.
