   Sammanfattning : Today humankind is facing numerous sustainability challenges that require us to question CO2 intensive practices like those present in the transport and energy sector. To meet those challenges, many countries have adopted ambitious climate targets. Achieving such targets requires an understanding of the wider socio-technical context of transitions. LÄS MER

4. 3. Ru-Based Water Oxidation Catalysts : Development and Mechanistic Studies

   Författare :Andrey Shatskiy; Björn Åkermark; Martin Albrecht; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ruthenium; catalysis; water oxidation; artificial photosynthesis; organisk kemi; Organic Chemistry;

   Sammanfattning : Oxidation of water constitutes one of the most challenging processes in artificial photosynthesis, which aims at storing solar energy in the form of chemical bonds of high-energy fuels. To facilitate this process, efficient and durable water oxidation catalysts have to be developed and integrated into the complete photosynthetic cells. LÄS MER
