Abstract |
Herein we report the spontaneous phase transition of h-CoO to Co(OH)2 in deionized water, and their application to the water splitting reactions. The addition of water drives the phase transition of the h-CoO to Co(OH)2 nanocrystals. Interestingly, the non-native h-CoO only progressed in the phase transition reaction to Co(OH)2 in the presence of water. The phase transition is unfavorable in the case of c-CoO nanocrystals. Moreover, performing the phase transition of h-CoO on various substrates results in efficient chemical bonding between the Co(OH)2 and substrate without additional processes. The proficient interaction of Co(OH)2 on the substrate is suitable for application to the catalytic water oxidation reaction. |
