| dc.description.abstract | In the midst of a growing energy crisis, green energy is a central point of conversation. Green energy can be efficiently created in electrochemical devices via water electrolysis. Semiconductors can be used in electrochemical devices, specifically photoelectrochemical devices, that absorb light and convert the absorbed energy to split water. Strontium titanate (STO) nanoparticles is a large band gap semiconductor that has been shown to be highly efficient at absorbing UV light and using UV light to split water in the presence of a metal catalyst. While this is accepted for STO, this phenomenon is not understood fundamentally. Using electrochemical analytical techniques, metal catalyzed STO was investigated in order to begin to understand this phenomenon. While the results of macroscopic analysis of cobalt co-catalyzed STO was inconclusive, the pH dependence of STO’s varying crystal facets hinted towards charge selectivity at the surface. | en_US |
