  • Title: Cobalt Carbonate Hydroxide Nanowire Array on Ti Mesh: An Efficient and Robust 3D Catalyst for On-Demand Hydrogen Generation from Alkaline NaBH4 Solution.
    Author: Cui L, Sun X, Xu Y, Yang W, Liu J.
    Journal: Chemistry; 2016 Oct 10; 22(42):14831-14835. PubMed ID: 27513921.
    Abstract:
    In this work, for the first time, a cobalt carbonate hydroxide (Co(CO3 )0.5 (OH)⋅0.11 H2 O) nanowire array on Ti mesh (CHNA/Ti) was applied to drive the dehydrogenation of alkaline NaBH4 solution 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 NaBH4 with a hydrogen generation rate of 4000 mL min-1  gCo-1 and a low apparent activation energy of 39.78 kJ mol-1 and offers an attractive system for on-demand hydrogen generation.
