Solid-Phase Hydrogen Storage Based on NH₃BH₃-SiO₂ Nanocomposite for Thermolysis

Figure 5

Hydrogen evolution curves at 50°C (black), 80°C (red), 90°C (blue), 100°C (dark yellow), and 110°C (green). The corresponding Arrhenius plot to measure the activation energy of the thermal dehydrogenation reaction of AB in the presence of the SiO₂ NP catalyst is also available (Supplementary Material Fig. S6). Note that mechanically pressed composites were employed, as shown in Supplementary Material Fig. S5, and the AB content in each composite is equal to 80 wt%.
