The detection of molecular hydrogen in water using platinum modified boron doped diamond (Pt-BDD) was presented. A clear peak of hydrogen desorption was observed around −0.1 V in 0.1 M KCl solution. With a simple electrochemical pretreatment, the signal at Pt-BDD electrode was found to be higher and more stable compared to those using bare Pt electrode. The performance of the sensor was compared with gas chromatography method. The result shows a similar trend with either same or different concentration of H2. Lastly, the measurement was successfully conducted in the tap water even without addition of electrolyte. These result shows that Pt-BDD could be promoted as a good electrode candidate for sensing dissolved H2 in the water-based solution.
