- Abstract:
-
The Auparticles were synthesizedby chemical reductionmethod andcharacterized byXRD.SEM andBET.Catalyst specific surface areareached 32.12 m2/g.Thegas diffusion electrodes were prepared by screen-printing technology.Theelectrochemical sensorswereconstructedas athree—electrode cell system.The results show that thesensors have high sensitivity up to 1.2斗A(in 0.89 ms/m3HF)tohydrogen fluoride gas,and the response andrecovery time are45 S and 15 S,respectively.Moreover,the sensors have good consis— tency of productquality,reproducibility of signal and long—term stability.The amperometric sensors are suit— able to detect the low concentration in atmosphere.
