  2. 6. Catalytic Water Production from First-Principles Calculations

    Author : Gustav Karlberg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; platinum; Monte Carlo; first-principles; hydroxyl; transition metals; density functional theory DFT ; Metropolis; oxygen; water; water production reaction; hydrogen;

    Abstract : The main subject of this thesis is the catalytic water production reaction on metal surfaces. This reaction is of great current interest due to its importance in fuel cells, a clean and efficient way to convert chemical energy into electrical. READ MORE

  4. 7. Reactions of aqueous radiolysis products with oxide surfaces : An experimental and DFT study

    Author : Cláudio Miguel Lousada Patrício; Mats Jonsson; Jean-Philippe Renault; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; hydrogen peroxide; hydrogen production; metal; oxides; lanthanide; catalysis; density functional theory; surface; reactions; chemistry; SRA - Energy; SRA - Energi; SRA - Production; SRA - Produktion;

    Abstract : The reactions between aqueous radiolysis products and oxide surfaces are important in nuclear technology in many ways. In solid-liquid systems, they affect (and at the same time are dependent on) both the solution chemistry and the stability of materials under the influence of ionizing radiation. READ MORE

  5. 8. Organic electronic materials for hydrogen peroxide production

    Author : Maciej Gryszel; Eric Glowacki; Magnus Jonsson; Erin Ratcliff; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydrogen peroxide; catalysis; organic materials; electronics;

    Abstract : Hydrogen peroxide (H2O2) is an important oxidant, used in various fields of industry, such as paper manufacturing, production of polymers, detergents, and cosmetics. Considering that the molecule degrades only to H2O and O2, it is regarded as a green chemical. READ MORE

  6. 9. Appraisal of strategies to improve thermophilic hydrogen production exploiting Caldicellulosiruptor species

    Author : Eoin Byrne; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Caldicellulosiruptor; Hydrogen; osmotolerance; Biorefinery; Osmolarity; Adaptive laboratory evolution; Co-culture; Volumetric productivity; Methane; Polyhydroxybutyrate; Coprothermobacter proteolyticus;

    Abstract : The transition from a fossil to a bio-based economy is of vital importance to stem the effects of ongoing climate change.This bio-based economy will necessitate the production of both biofuels and chemical compounds from biologicalsources. READ MORE

  7. 10. Hydrogen production from fossil fuels with carbon dioxide capture, using chemical-looping technologies

    Author : Magnus Rydén; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chemical-looping combustion; carbon capture and storage; partial oxidation; Chemical-looping reforming; synthesis gas; hydrogen; steam reforming;

    Abstract : Carbon capture and storage have been receiving increasing interest lately, mainly as an option to reduce CO2 emissions from the power sector. The concept could be adapted for production of H2 as well, which would provide a carbon free energy carrier that could be used for example as transportation fuel. READ MORE
