Hydrolysis of sodium borohydride (NaBH) can effectively produce hydrogen, but it relies on an affordable catalyst; this research examines silica and phosphorylated silica as potential catalysts.
The catalysts were created using a sol-gel method, with tetraethyl orthosilicate for silica and phosphoric acid for phosphorylation, and they were analyzed using various techniques like FT-IR and XRD.
The phosphorylated silica (SP-PA) showed a significantly higher hydrogen production rate (762.4 mL/min/g) compared to regular silica (133 mL/min/g), indicating that the acidic properties of SP-PA enhance its catalytic performance.
