Photo-catalysis offers the possibility to utilize solar energy to split water, thereby extracting chemical energy in the form of hydrogen. The general challenge is to synthesize a material with the right electronic and chemical properties for efficiently driving the process, while being sustainable in terms of stability and costs. The focus of this bachelor thesis is photo-electrocatalytic splitting of water on modified iron oxide thin films. Through various surface treatments and modification of thin film compositions, this material has shown that its water splitting properties can be improved.
