dc.description.abstractIn this study, the effect of Alternating Current and Direct Current Dielectric Barrier Discharge cold plasmas on the catalytic activity of CoeCreB based catalysts reduced from CoCl2$6H2O ? Cr(NO3)3$9H2O is investigated. The catalytic properties of CoeCreB catalysts utilized in hydrogen generation from the hydrolysis of NaBH4 are examined in the plasma mediums depending on various voltages applied to plasmas. The catalysts are produced by AC plasma and DC plasma methods separately. In the presence of plasma-produced catalyst, the hydrolysis reactions complete within shorter time intervals than in the presence of non-plasma produced catalysts. The best chosen AC plasma-produced CoeCreB catalyst completes the hydrolysis reactions in 5 min; while the non-plasma produced catalyst completes the same reactions in 20 min. The hydrolysis reaction of sodium borohydride with CoeCreB catalyst produced in AC plasma media is controlled by zero order reaction whereas the same reaction is controlled by first order reaction in the presence of COeCreB catalyst produced in DC plasma medium. The activation energy carried out in the presence of CoeCreB catalyst produced in AC plasma and DC plasma mediums was found as 16.17 kJ$mol1 and 18 kJ$mol1, respectively.en_US
