Hydrogen Generation by Shimalite Ni Catalyst

Platinum is a suitable electrode for electrochemical production of hydrogen, but itis expensive and its resource availability very limited. shimalite ni is a catalyst for reductionin gas chromatography, which commonly used for methane conversion of carbon monoxide,carbon dioxide, formaldehyde, and so on. in this study carbon paste electrode was modifiedby the proposed catalyst and the modified electrode was used for electrochemical hydrogenevolution in acidic media. some parameters including oil and catalyst percentage in the paste,ph and supporting electrolyte type were examined. the best conditions and composition was13% catalyst, 20% paraffin oil and 1.5 m h2so4. due to the low cost and high performanceof this catalyst, it can be considered a good candidate for production of hydrogen withoutusing pt. also against very reports, in this study by applying successive potential cycles onthe modified electrode surface, the performance of the electrode improves.
