Abstract
Here we demonstrate high density that hydrogen nano-bubble (HNB) up to -3.45 wt"/o can be efficiently generated and stored via an electron radiolysis assisted abstraction reaction (RAAR) in an encapsulated quasi-2D water reservoir containing organic molecules. The gravimetric capacity and loss rate in our experiment are -3.45 wt% and 0.17(g/h)/kg, respectively in ambient condition, which fall closely to the OOE targets. A TEM equipped with a continuous flow holder with a quasi-2D water reservoir is utilized for in-situ generation and storage of HNB.
