    Abstract : Reliable energy supply is a major concern and crucial for development of the global society. To address the dependency on fossil fuel and the negative effects of this reliance on climate, there is a need for a transition to cleaner sources. An attractive solution for replacing fossil-based products is renewable substitutes produced from biomass. READ MORE

  4. 2. Towards Artificial Photosynthesis: Exploration of Efficient First-Row Transition Metal-Based Water Oxidation Catalysts

    Author : Lizhou Fan; Licheng Sun; Thomas Wågberg; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Artificial photosynthesis; Water oxidation; Heterogeneous catalyst; Electrochemistry; Electronic structure; Kemi; Chemistry;

    Abstract : Artificial photosynthesis provides a promising strategy for sustainable energy harvesting, yet its overall efficiency is limited by the water oxidation reaction. The subject of this thesis focuses on the exploration of highly efficient cost-effective heterogeneous catalysts for water oxidation, and the investigation of essential catalyst structure-activity relationships.

  5. 3. Computational Studies on Homogeneous Water Oxidation Catalysts

    Author : Ge Li; Mårten S. G. Ahlquist; Moyses Araujo; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computational studies; homogeneous; water oxidation catalysts; ruthenium; iron; mechanisms; Teoretisk kemi och biologi; Theoretical Chemistry and Biology;

    Abstract : To combat the increasing energy demand and climate change, artificial photosynthesis is a promising approach to producing renewables by storing energy into chemicals and fuels. Water oxidation, responsible for offering electrons and protons to the reduction reactions, suffers from slow kinetics. READ MORE
