| 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 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. |
