%X Within the project the electronic structure and chemical reactions at interfaces are investigated by using the quantum chemical methods density functional theory (DFT) and density-functional tight binding (DFTB).  The research covers a broad spectrum of topics ranging from sustainable energy materials for solar hydrogen production to the wear and friction in tribological contacts including mechanically induced chemical reactions of lubricant and additive molecules at surfaces. A common feature of the different studies are surface reactions of molecules induced by different driving forces such as excited charge carriers or external mechanical load. Here, selected examples of our studies are presented where the splitting of water molecules at surfaces and interfaces plays a key role. We start with the ab initio DFT investigation of unconventional U3O8//Fe2O3 heterostructures which are used to split water molecules with the purpose of solar hydrogen production and conclude with DFTB simulations of water lubricated carbon coatings where water splitting can lead to extremely low friction, also known as superlubricity.
