The photoelectrochemical water splitting of bismuth vanadate and nickel oxide is investigated. The goal is to use these semiconductors to generate solar fuels and to gain an understanding of the reaction. Bismuth vanadate, as a photoanode, is deposited in different ways and investigated ex-situ and in-situ. In addition, bismuth vanadate is nanostructured to investigate a potential plasmon effect on the oxygen evolution reaction. As photocathode, organometallic catalysts deposited on nickel oxide are investigated. With the help of these catalysts the reduction of NAD+ to NADH is studied. Due to the low stability of this system, various changes are made to the preparation to slow down the decrease of the photocurrent. In addition, a new cell design for photoelectrochemical measurements is presented in this thesis and the achievable improvements to previous designs are highlighted.
