From: Practical H2 supply from ammonia borane enabled by amorphous iron domain

a Hydrogen evolution curves of the hydrolysis of AB catalyzed by Fe Foam, commercial Fe2O3 NPs, and R-Fe2O3 Foam (800 oC), respectively. b, c Stability test of R-Fe2O3 Foam (800 oC) within 900 h. After 900 h, there is no obvious decline. d–f Hydrolysis process of AB catalyzed by R-Fe2O3 Foam (800 oC). g Hydrogen evolution curves catalyzed by R-Fe2O3 Foam (800 oC) with different sizes. h Area activities of R-Fe2O3 Foam (800 oC) with different sizes. i Picture of R-Fe2O3 Foam (800 oC) with a size of 10 × 10 cm2.
