Cobalt nanoparticles supported elastic foam (Co-F) was prepared by coating commercial polyurethane foam with cobalt nanoparticle loaded hybrids (Co/rGO). The Co-F was applied to catalyze hydrolysis reaction of sodium borohydride to produce hydrogen gas. Co-F has large surface area and interconnected pores, so it showed outstanding activity in catalyzing the hydrolysis reaction and achieved a hydrogen production rate of 33.2 mL min(-1). The conditions for Co/rGO and Co-F preparation as well as reaction conditions like the reaction temperature, the concentration of NaBH4 and pH value all affected the catalytic hydrolysis of NaBH4. The Co-F could be easily recovered by taking out, pressing and rinsing in distilled water, and it exhibited almost unfaded catalytic activity in the reusage. The unique properties will make Co-F potential applications in catalytically chemical reactions. (C) 2017 Elsevier B.V. All rights reserved.
