摘要：

Hydrogen can be catalytically generated on a large scale by hydrolysis of NaBH4. In this communication, we describe the development of cobalt phosphide nanosheet arrays on Ti mesh (CoP/Ti mesh) as a robust and highly active monolithic catalyst for the hydrolytic dehydrogenation of NaBH4 in alkaline solutions. A hydrogen generation rate of 6100 mL((H2)) min(-1) g((CoP))(-1) and an activation energy of 42.01 kJ mol(-1) were achieved under air-saturated atmospheric conditions, which are superior to those of most reported catalysts, with good durability and reusability.
