Different Pt-Carbon catalysts have been synthesized by hard templating route and have been employed for production of hydrogen from liquid phase HI decomposition at 160 °C temperature. The physical properties and catalytic activities of these catalysts are compared with that of the platinum on activated carbon catalysts. These catalysts have been characterised by X-Ray diffraction, Raman, SEM and BET surface area. Eluant analysis has been carried out using ICP-OES for evaluation of the extent of noble metal leaching under the catalytic activity test conditions. From the present study we have concluded that MCM-41 based Pt/carbon has higher catalytic activity and stability than other Pt/carbon catalysts.
► High surface area Pt/carbon prepared using hard template. ► All catalysts are stable and catalytically active for liquid phase HI decomposition. ► Catalytic activity is favoured for mesoporous Pt/carbon catalyst. ► Microporous Pt/Carbon catalyst exhibit lower catalytic activity.
