The world energy crisis requires innovative solutions to end dependence on fossil fuels and develop a reliable energy source. Hydrogen gas can be produced with net zero carbon emissions by utilizing a solar catalytic system. This research will develop a cost-efficient system that will photocatalytically produce Hydrogen. Ce:UiO66-NH2 will be investigated as a candidate photocathode. Dye photodegradation will be used to reproduce results that indicate photoactivity in Ce:UiO66-NH2. UiO66-NH2 will be studied to compare photoactivity with and without Ce substitution in the metal organic framework. Furthermore, the electrochemical properties of Ce:UiO66-NH2 functionalized with PANI(Polyaniline) will be studied via cyclic voltammetry by doping a glassy carbon electrode. Variations of this study will include the use of TTF(tetrathiafulvene) and TCNQ(7,7,8,8-tetracyanoquinodimethane) instead of PANI. Initial characterization of Ce:UiO66-NH2 was through UV-Visible Direct Reflectance Spectroscopy to determine the band edge of the analytes. This work will ultimately lead to the development of a candidate photocathode with Ce:UiO66-NH2 aimed to produce Hydrogen for the purpose of creating a net zero carbon emission fuel.
