| 中文摘要 | gold nanoparticles supported on multi-walled carbon nanotubes (au/mwcnts) were prepared as electrocatalysts for an electrochemical sensor of acetylene. the catalysts were characterized by transmission electron microscopy (tem), x-ray diffraction (xrd) and x-ray photoelectron spectroscopy (xps). the electrochemical experiments showed that the catalysts exhibited a distinctly higher activity for the acetylene electro-oxidation than au-nps and au/c catalysts. in typical cyclic voltammograms, the onset potential of au/mwcnts for the acetylene oxidation is 0.73 v. which is 0.19 v more negative than that of au-nps. the acetylene sensor test showed good linear response towards acetylene concentration in a wide range from 10 ppm to 50 ppm with a steady response current for 300 s, good sensitivity of 80 na/ppm and fast 90% response time (t(90)) of 25 s to 50 ppm acetylene. all the results indicate a good potential application of this sensor in the detection of acetylene.
