“…Pulsed Laser Deposition is a PVD (Physical Vapor Deposition) technique that has been employed for the preparation of catalysts for SB and AB hydrolysis. Co-B thin films and more recently, Co nanoparticles on a B film have been prepared by this method [21][22][23][24]. This technique allows to deposit high density granular films of different roughness with the target stoichiometry.…”

“…This technique allows to deposit high density granular films of different roughness with the target stoichiometry. [21][22][23][24][25] Magnetron sputtering is a PVD technique that allows the deposition of thin films with precise controlled thickness over a wide variety of substrates due to the low deposition temperature of the process. It can be easily scaled to industrial processes and is a low cost process without the need of precursors avoiding emissions of toxic by- This technique has proven before to be a versatile tool to prepare nanostructured and porous materials in our group [26][27][28].…”

Supported Co catalysts were prepared for sodium borohydride and ammonia borane hydrolysis by magnetron sputtering for the first time under different conditions. Ni foam was selected as support. Deposition conditions (time, pressure, and power) were varied to improve catalytic activity. A decrease in deposition power from 200 to 50 W, leads to a decrease in crystallite and column size and a higher activity of catalysts. The increase in deposition pressure from 1.5x10-2 to 4.5x10-2 mbar produces same effect but in this case the enhancement in activity is higher because amorphous materials were obtained. The highest activity for SB hydrolysis was 2650 ml.min-1 .g cat-1 for the 50W Co 4.5 (4h) sample (E a =60±2 kJ.mol-1). For AB hydrolysis activity for the 50W Co 3.2 (4h) sample was similar. Durability of the thin films was tested for both reactions upon cycling (14 cycles). Diluted acid washing was effective to recover the activity for sodium borohydride reaction but not for ammonia borane hydrolysis. The strong Co-NH 3 interactions explain the non-efficiency of the acid washing.

Hydrogen storage is still one of the most significant issues hindering the development of a “hydrogen energy economy”. Ammonia borane is notable for its high hydrogen densities. For the material, one of the main challenges is to release efficiently the maximum amount of the stored hydrogen. Hydrolysis reaction is a promising process by which hydrogen can be easily generated from this compound. High purity hydrogen from this compound can be evolved in the presence of solid acid or metal based catalyst. The reaction performance depends on the morphology and/or structure of these materials. In this review, we survey the research on nanostructured materials, especially porous materials for hydrogen generation from hydrolysis of ammonia borane.
