Ferritin-bound Platinum Nanoparticles in Hydrogen Production
Hydrogen gas has been hailed as the fuel of the future. Unfortunately, significant problems with its production, storage, and transportation prevent its widespread use. Hydrogen gas synthesized by Ferritin-bound platinum nanoparticles (FBPNs) can resolve these problems. The optimum uv light exposure time for making FBPNs was explored. To synthesize FBPNs, 150 µg/mL Ferritin, 2 mM Pt2+, 50 mM NaCl, 30 mM sodium citrate, and 30 mM Tris were reacted under a uv lamp with stirring. Samples were separated into fractions using size-exclusion chromatography. The fractions were tested for protein concentration using the Bradford protein assay and for platinum content using ICP-MS. The optimum time for the production of FBPNs was 60 minutes of uv exposure with 0.16 platinum nanoparticles per Ferritin being formed. Using the FBPNs, hydrogen gas was synthesized. Hydrogen gas was synthesized in amounts up to 9000 ppm. While the results are preliminary, they suggest that with continued uv exposure, the concentration of reactants was depleted thereby inhibiting the growth of more nanoparticles. The successful production of hydrogen shows that this a replicable process.
