1. 1. Outer Coordination Spheres Engineering of Ru-based Molecular Water Oxidation Catalysts

   Författare :Tianqi Liu; Licheng Sun; Julio Lloret-Fillol; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; solar fuels; water oxidation; catalysis; ruthenium complex; Ru-bda; Ru-pda; outer coordination sphere; hydrophobic interactions; Kemi; Chemistry;

   Sammanfattning : The outer coordination sphere plays a vital role in metalloenzyme catalysis, while this principle is relatively less considered in the design of man-made molecular catalysts. This thesis investigates the role of outer coordination spheres in water oxidation by a series of ruthenium-based complexes. LÄS MER

   Sammanfattning : Chemistry has a tremendous impact on everyone’s life, although society does not always realize its power and ubiquity. In recent years, improved economy and sustainability of chemical processes has become a worldwide priority. LÄS MER

4. 3. Computational Studies on Homogeneous Water Oxidation Catalysts

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

   Sammanfattning : 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. LÄS MER

5. 4. From Molecular Catalysts to Hybrid Electrodes: A Theoretical Guide

   Författare :de Gracia Triviño Juan Angel; Mårten S. G. Ahlquist; Aleksandra Vojvodic; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Theoretical Chemistry and Biology; Teoretisk kemi och biologi;

   Sammanfattning : The industrial revolution thrived our society to great technological advancement and a shift from an agrarian to an industrial society. Besides this fact, the side effect has been the development of a society highly dependent on energy, and the main sources of energy are based on non-renewable fossil fuels. LÄS MER

7. 5. Theoretical Studies on Water Oxidation Catalysts - from Solvent to Interfaces

   Författare :Shaoqi Zhan; Mårten Ahlquist; Núria López; KTH; []
   Nyckelord :Teoretisk kemi och biologi; Theoretical Chemistry and Biology;

   Sammanfattning : Water splitting contains two half-reactions, the water oxidation reaction and the hydrogen reduction reaction. In water oxidation, protons and electrons will be generated to offer two elemental components for production of fuels, such as H2 and CH3OH. LÄS MER
