Mesoporous high entropy oxides for oxygen evolution reaction (photo)catalysis

The primary research objective of the TWOB project is to systematically optimize electrocatalysts and semiconducting photoelectrodes for grid-independent, tandem cell-based photoelectrochemical water splitting.

Interface analysis between halide-based composite solid electrolyte with lithium metal anode and high voltage cathode

The stability in batteries is dictated by the interfaces of the electrolyte and the electrodes.

Carbon materials from oil sands-derived asphaltenes for next-generation sodium-ion batteries – from mechanistic investigations to life cycle analysis

Lithium-ion batteries (LIBs) dominate energy storage, but rising lithium demand and environmental concerns drive research into sodium-ion batteries (SIBs). Germany aims to advance eco-friendly SIB technology, focusing on cost-effective materials. Asphaltenes, abundant oil sands by-products in Canada, offer a low-cost alternative but are largely wasted

Dynamic operation of Rutile-based oxygen evolving electrocatalysts

In the DaCapo project, the dynamic operation of electrocatalysts for the water splitting reaction, specifically the oxygen evolution reaction, is investigated as a means of improving the hydrogen production efficiency. As model system, Iridium oxide, ruthenium oxide, and mixtures thereof are chosen. In acidic electrolytes they show a high efficiency and sufficient stability to be employed at the industrial scale.

Electronic Structure and Redox Properties of Iron in Different Environments Studied by Valence and Core Level Spectroscopies

The electronic properties of iron such as the band structure, work function, ionization potential and electron affinity, which determine its redox properties in solid state and liquid phase reactions, sensitively depend on the chemical, coordinating environment of the Fe species in question.

Characterization and design of inner and outer interfaces in O2-evolving electrodes for alkaline water splitting

The BMBF is currently funding the flagship project H2Giga, which aims at bringing innovative and more efficient electrolysers into series production. Within that project, the PrometH2eus consortium combines fundamental and applied science to synthesize, evaluate and optimize new materials for the oxygen evolution reaction in alkaline electrolysis.
