Abstract

Chemical hydrides show promise in solving the storage challenge, which is one of the important problems in the widespread use of hydrogen. An important issue that needs to be developed regarding chemical hydride storage is the high speed of hydrogen release. For this reason, this study focuses on hydrogen release rates of alkaline sodium borohydride with different prepared catalysts. Different amounts of surfactant as Triton X-100 including CoB catalysts have been prepared and hydrogen release rates (HGR) have been compared. Results indicate that Triton addition has different effects, but optimum ratio improves catalyst performance. 150 µl Triton addition (CoB-T150) raises HGR from 12.61 LH2*g-1cat*min-1 to 17.69 LH2*g-1cat*min-1, as 40.2% increase compared to pure CoB catalyst. As a result, surfactants offer alternative to enhance catalyst performance and need further research.
