3. Mononuclear Ruthenium Complexes that Catalyze Water to Dioxgen Oxidation
Sammanfattning : The theme of this thesis is the development of mononuclear Ru-based complexes that are capable of catalyzing the water oxidation (or O2-evolving) reaction, e.g. 2 H2O → O2 + 4 H+ + 4 e−. Several families of mononuclear Ru water oxidation catalysts were designed and prepared. LÄS MER
4. Supramolecular chemistry based on redox-active components and cucurbit[n]urils
Sammanfattning : This thesis describes the host-guest chemistry between Cucurbit[7]uril (CB[7]) and CB[8] and a series of guests including bispyridinium cations, phenols and napthalenes. These guests are bound to ruthenium polypyridine complexes or ruthenium based water oxidation catalysts (WOCs). LÄS MER
5. Molecular Copper and Ruthenium Water Oxidation Electrocatalysts for Light-Driven Water Splitting
Sammanfattning : In recent years, there has been a growing awareness of the need to transition to renewable energy to mitigate the effects of climate change and reduce greenhouse gas emissions. Governments, businesses, and individuals are investing in renewable energy infrastructure and technologies to create a more sustainable energy future. LÄS MER
