This study has studied the activity of the hydrolysis reaction with the plasma effect on the CoBi bimetal nano-catalyzer. Sodium borhydrate is used as a source of hydrogen. The synthesized catalyst has been analyzed with the surface electron microscope (TEM) and surface size distribution (BET). To study the effect of plasma, various parameters were applied, such as the plasma power of the catalyst (60%, 80% and 100%), the plasma duration (10, 15 and 20 minutes) and the inert gas (CO2, N2 and Ar) given to the plasma environment. The result of these applied parameters was added to the hydrolysis reaction in the presence of 30 oC, 10 ml of water, 1% NaBH4, 5% NaOH and 25 mg catalysts. Referring to the completion periods of hydrolysis reaction, the appropriate conditions for activating the CoBi catalyst were determined to be the application of plasma for 15 minutes with 80% plasma power in the CO2 gas environment.

In this study, the activity of CoBi bimetallic nanocatalyst in hydrolysis reaction with plasma effect was investigated. Sodium borohydride was used as the hydrogen source. The surface of the synthesized catalyst was analyzed by transmission electron microscopy (TEM) and surface size distribution (BET). Various parameters such as catalyst plasma power (60%, 80% and 100%), plasma time (10, 15 and 20 min) and inert gas (CO2, N2 and Ar) given to the plasma medium were applied to examine the plasma effect. The catalyst formed as a result of these applied parameters was added to the hydrolysis reaction in the presence of 30 oC, 10 ml of water, 1% NaBH4, 5% NaOH and 25 mg of catalyst. Based on the completion times of the hydrolysis reaction, it was determined that the appropriate conditions for activating the CoBi catalyst were to apply plasma for 15 minutes with 80% plasma power in the CO2 gas environment
