title: Cobalt Carbonate Hydroxide Nanowire Array on Ti Mesh: An Efficient and Robust 3D Catalyst for On-Demand Hydrogen Generation from Alkaline NaBH4Solution.
abstract: In this work, for the first time, a cobalt carbonate hydroxide (Co(CO3)0.5(OH)⋅0.11 H2O) nanowire array on Ti mesh (CHNA/Ti) was applied to drive the dehydrogenation of alkaline NaBH4solution for on-demand hydrogen production. Compared with other nanostructured Co-based catalyst systems, CHNA/Ti can be activated more quickly and separated easily from fuel solutions. This self-supported cobalt salt nanowire array catalyst works as an efficient and robust 3D catalyst for the hydrolysis reaction of NaBH4with a hydrogen generation rate of 4000 mL min-1gCo-1and a low apparent activation energy of 39.78 kJ mol-1and offers an attractive system for on-demand hydrogen generation.
