Doctoral Dissertations
The aim of this dissertation was to optimize systems integrating the photosystem I (PSI) redox protein, which is involved in photosynthesis, with noble metals for electron transfer to show its versatility: 1) in solution coupled with platinum to mediate hydrogen evolution and 2) on a planar gold surface for electricity production.
Response surface methodology was utilized to study variables that affect hydrogen (H2) yield from platinized-PSI. Light intensity, temperature, and platinum concentration were varied during the platinum-photo-reduction process. Analysis of the effects of the variables on H2 yield allowed for determination of a condition for optimized hydrogen …
