Water splitting offers the opportunity for storing solar energy and, thus, producing carbon-neutral and renewable solar fuels. The process, known as artificial photosynthesis, is limited by the electrocatalytic conversion of water into molecular oxygen. El ...
Designing cost-effective electrocatalysts for electrochemical water splitting to generate the hydrogen energy as a future energy source is pivotal. An excellent catalyst should show high catalytic activity for both hydrogen evolution reaction (HER) and oxy ...
This thesis deals with different aspects of renewable energy transformation and storage concepts and connects them. Although renewable energy installations are growing worldwide, their use is limited by storage technologies. As such, water splitting for hy ...
Renewable resources of energy are increasing their share in our energy portfolio thanks to the technological advancements and an increasing environmental awareness in society. Although the cost of power generation from these resources has been reduced to r ...
Electrocatalysts play an important part on the route towards environmental friendly energy sources. They support modern technologies like fuel cells to move further away from the utilization of fossil fuels and the resulting CO2 emission into our atmospher ...
Here we report an organocatalytic double Ugi reaction combining the enantioselective process and ee enhancement in a single operation to afford the chiral Ugi products with very high ee values. Both bisisocyanides and bisanilines tethered by carbonate and ...
Colloidal nanocrystals (NCs) are among the most modular and versatile nanomaterial platforms for studying emerging phenomena in different fields thanks to their superb compositional and morphological tunability. A promising, yet challenging, application in ...
Energy Storage in the chemical bonds of water, a process accessible through electrochemical conversion, is a simple approach to compensate supply fluctuation common to sustainable energy production such as wind and solar. However, the water cycle is limite ...
Photoelectrochemical (PEC) cells are attractive for storing solar energy in chemical bonds through cleaving of water into oxygen and hydrogen. Although hematite (alpha-Fe2O3) is a promising photoanode material owing to its chemical stability, suitable band ...
The present invention relates to a nickel iron diselenide compound of general formula (I): NixFe1-xSe2, wherein 0 < x < 1, and to the use of this compound as a precursor of catalysts for oxygen evolution reaction (OER). This invention also concerns methods ...
