Photocatalysis - a powerful tool for the generation of Sun Fuels from Water and Carbon Dioxide? — •Henrik Junge — Leibniz-Institut für Katalyse e.V. an der Universität Rostock

One of the central challenges of the next decades is the sufficient and sustainable supply of energy. The conversion of the almost unlimited available energy of sunlight into stored chemical energy by means of photo- or electrocatalytic water splitting into oxygen and hydrogen is a benign objective. Besides hydrogen, further value added products like e.g. carbon monoxide, formic acid, methanol or methane are of special interest. While multistep processes, consisting of a wind power plant or photovoltaic cells, an electrolysis cell and carbon dioxide hydrogenation to form these products are available at least at a small scale, the development of a one step process is pending and basic research is still necessary. Nevertheless, some significant progress has been already achieved. Due to lower costs, the replacement of noble metal catalysts by cheap 3d metals like iron, nickel and cobalt is of special interest for these fields. Within the presentation various relevant examples of catalyst development for these topics will be provided.
