title: Self-supported spinel FeCo2O4nanowire array: an efficient non-noble-metal catalyst for the hydrolysis of NaBH4toward on-demand hydrogen generation.
abstract: NaBH4has been considered as one of the most advantageous candidates for chemical hydrogen storage, but it is still a huge challenge to design efficient non-noble-metal catalysts for on-demand hydrogen generation from NaBH4hydrolysis. In this paper, we demonstrate for the first time that a spinel FeCo2O4nanowire array supported on carbon cloth (FeCo2O4NA/CC) behaves as an efficient earth-abundant catalyst toward NaBH4hydrolysis in alkaline solutions with an activation energy of 44.98 kJ mol-1. Such FeCo2O4NA/CC offers a hydrogen generation rate of 2551 ml min-1g-1under ambient conditions, with good stability and reusability. Its use as an ON/OFF switch for on-demand hydrogen generation is also demonstrated successfully.
