“…The first step (Equation (2)) of the reaction is reversible surface adsorption and dissociation of borohydride ion to form MH and MBH 3 -[where M is the active catalysts surface]. In second step (Equation (3)) charge associated with MBH 3 -became reversible with catalyst surface (M) and borane (BH 3 ). This step is referred as the anodic step of the hydrolysis reaction.…”

“…are the premier materials due to their light weight, high hydrogen storage capacity and ability to release hydrogen at RT through hydrolysis [2]. Sodium borohydride is the most investigated chemical hydride among them due to its high hydrogen storage capacity (10.8 wt%), stability in alkaline solution, non-toxicity and pure hydrogen production [3][4][5]. The hydrolysis reaction of sodium borohydride at STP proceeds as Equation (1) [6].…”

Aluminium phosphate and bentonite supported Co-B catalyst were synthesized via two step impregnation-reduction method for sodium borohydride hydrolysis. The synthesized catalysts were characterized by XRD, FTIR, XPS, FE-SEM, FE-TEM, BET, ICP-AES techniques and tested for NaBH 4 hydrolysis reaction. The results demonstrated that the synthesized supported Co-B catalysts greatly facilitate the NaBH 4 hydrolysis reaction. Highest hydrolysis rate observed for Co-B/AlPO 4 and Co-B/bentonite catalysts are 6.50 and 3.91 L min −1 g −1 , respectively, with 2 wt% NaBH 4 , 5 wt% NaOH solution at 30 °C. The hydrogen generation rate was found to increase with experimental temperature. Activation energy for the hydrolysis reaction was observed to be 37 and 40.2 kJ mol −1 for Co-B/AlPO 4 and Co-B/bentonite catalysts, respectively.

Boron-based materials are potential solutions in the field of energy. They have been regarded as hydrogen storage materials, liquid fuels of direct liquid-fed fuel cells (DLFCs), electrolytes of battery, and/or energetic substances.A typical example is sodium borohydride (NaBH 4) . In sodium hydroxide-stabilized aqueous solutions, it is seen as an efficient H 2 generator or a performing fuel of DLFCs. Actually, it plays a wider role; it is also the precursor of several boron-based materials of interest in the field of energy. In other words, it is indirectly considered for other energy applications, i.e. solid electrolytes of all solid-state batteries and hypergolic fuel. De facto sodium borohydride has become a key material in the field of energy. This is discussed in the present article, and it is highlighted that sodium borohydride may be clearly seen as a "rough diamond" for Turkey.
