Title

Synthesis of Hydrogen Gas Utilizing Ferritin-Bound Platinum Nanoparticles

Abstract

While the benefits of hydrogen gas as a clean fuel source have been explored, and hydrogen vehicles have even been proposed, currently the production of hydrogen gas is done mainly through processes involving hydrocarbons. One way in which hydrocarbons can be circumvented is through the production of hydrogen gas using ferritin-bound platinum nanoparticles (FBPNs). In order to create FBPNs, we combine ferritin, platinum ions, NaCl, sodium citrate, tris buffer and react under UV light. Nanoparticle formation has been confirmed by TEM imaging as well as mass spectrometry (ICP-MS). Our reacted sample is separated into fractions using size-exclusion chromatography. The fractions are tested for ferritin using the Bradford and Lowry protein assays. The chromatography fractions that display large concentrations of proteins also show corresponding peaks in the platinum levels, as further evidence of FBPNs. The fraction containing the majority of our FBPNs can then be used as a catalyst in combination with methyl viologen and citrate to produce hydrogen gas, and our preliminary results show that we have successfully synthesized hydrogen.
