摘要

This paper is reports on the effect of plasma treatment with various discharge regimes and plasmasources (Ar, O2 and CO2) on hydrogen capacity of carbon electrodes. Among various modifications ofcarbon materials being undertaken to increase hydrogen storage capacity, plasma treatment seems tobe quite interesting one. Obtained results confirmed that surface properties modified by plasmatreatment play an important role in hydrogen electrosorption process. The highest hydrogen capacity,-1 i.e., 425 mAh g (1.56 wt.%) was recorded for electrode after 15 seconds of Ar-plasma treatment,whereas the lowest value was observed also for electrode after Ar-plasma treatment but with longertime, i.e., 300 seconds. The results for samples with O2 and CO2 plasma source are rather comparablewith the reference sample. Unfortunately, no direct dependency between plasma type, time oftreatment and hydrogen capacity was found, however, an repeatable increase of hydrogen stored on theelectrodes treated by Ar-plasma type was observed.
