“…Most of the researches related to this system focused on improving the slow kinetics of the scheme 1. In this way, intensive works have demonstrated that noble metal catalysts and cobalt based catalysts were very efficient [1][2][3][4][5][6][7][8][9][10]. However, it is paramount to note that beyond the kinetically limitations of the hydrolysis reaction, the main issue to be considered is the practical achievable hydrogen storage capacity [11][12] that can be expressed by the gravimetric hydrogen storage capacity (GHSC).…”

The binary phase diagram NaBO 2-H 2 O at ambient pressure, which defines the different phase equilibria that could be formed between borates, end-products of NaBH 4 hydrolysis, has been reviewed. Five different solid borates phases have been identified: NaBO 2 •4H 2 O (Na[B(OH) 4 ]•2H 2 O), NaBO 2 •2H 2 O (Na[B(OH) 4 ]), NaBO 2 •2/3H 2 O (Na 3 [B 3 O 4 (OH) 4 ]), NaBO 2 •1/3H 2 O (Na 3 [B 3 O 5 (OH) 2 ]) and NaBO 2 (Na 3 [B 3 O 6 ]), and their thermal stabilities have been studied. The boundaries of the different Liquid+Solid equilibria for the temperature range from-10 to 80 °C have been determined, confirming literature data at low temperature (20 °C ~ 50 °C). Moreover the following eutectic transformation, Liq. → Ice + NaBO 2 •4H 2 O, occurring at-7 °C, has been determined by DSC. The Liquid-Vapour domain has been studied by ebullioscopy. The invariant transformation Liq. → Vap. + NaBO 2 •2/3H 2 O has been estimated at 131.6 °C. This knowledge is paramount in the field of hydrogen storage through NaBH 4 hydrolysis, in which borate compounds were obtained as hydrolysis reaction products. As a consequence, the authors propose a comparison with previous NaBO 2-H 2 O binary phase diagrams and its consequence related to hydrogen storage through NaBH 4 hydrolysis.

“…In a typical reaction, Co-F cubes were put under a 500 rpm stirring rate at 20 C in a 50 mL flask that contains 20 mL NaBH 4 aqueous solution to start the hydrolysis reaction of NaBH 4 . The generated hydrogen was measured with the water displacement method [40][41][42]. The volume of hydrogen gas was recorded by an inverted water-filled graded cylinder.…”

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 NaBH 4 and pH value all affected the catalytic hydrolysis of NaBH 4. 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.

“…In addition to the precious metal and transition metal catalyst [15], some non-noble metal catalysts have recently obtained the rapid development, such as Ni-B and Co-B [16,17] catalyst, etc. In these catalysts, the Co-B has been favored by researchers because of its excellent catalytic performance.…”

For the purpose of improving hydrogen release capacity of NaBH4, hydrogen generation performance of NaBH was catalyzed by Co2B and TiO2 compound with different mole ratio and percentage composition are investigated. The experiment mainly concentrated in the hydrogen generation rate and the hydrogen generation volume. The results indicate that the effects of hydrogen release of NaBH when the proportions and amount of Co2B/TiO2 are not obvious. Changing the proportions and the amount, the amount of hydrogen release by hydrolysis of NaBH4 are between 343- 375ml. However, the study on the rate of hydrogen release finds that the effects of the proportion and amount of the compound catalyst on the rate of hydrogen release are very marked. The rate of hydrogen release of the catalyst samples presents an obvious increase when the amount of Co2B/TiO2 is between 1-4%. Among all the samples of compound catalyst, the rate of hydrogen release of the sample with 5% Co2B/2TiO2 is the largest.
