Influence of platinization of mechanically activated nuclear grade graphite powders on the hydrogen adsorption process
Conference object (Published version)
MetadataShow full item record
Non-activated powder of nuclear grade graphite and powders of nuclear grade graphite that were milled for 10, 20 and 30 minutes are doped with 0.03% of platinum. XRD analysis of injtial and activated graphite powders was used for structural characterization. Hydrogen adsorption perfonned in isothermal conditions showed that platinization of powder samples of nuclear grade graphite decreases time needed for reaching adsorbent saturation during hydration. Simultaneously it was shown that platinization, due to the hydrogen spillower effect, increases adsorption capacity in a function of mechanical activation duration.
