    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Fe-air battery; Cu Sn-doped nanostructured iron electrodes; Alkaline electrolytes; Bi-functional OER ORR catalyst; perovskite spinel catalyst; NiFeOx; air electrode; Chemical Engineering; Kemiteknik;

    Sammanfattning : Energy storage system is an important component in the energy system based on variable renewable energy sources into the grid. Energy storage system could contribute to decarbonization, energy security, offset the demand and supply of the electricity sector, especially for the electric grid. LÄS MER

  3. 7. Chemically Modified Metal Oxide Nanostructures Electrodes for Sensing and Energy Conversion

    Författare :Sami Elhag; Omer Nour; Magnus Willander; Alberta Bonanni; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Metal oxide nanostructures; mixed metal oxide nano-compound; low temperature wet-chemical growth; chemically modified electrode; doping; surfactant; potentiometric sensor; chemical sensor and photo-electrochemical activity;

    Sammanfattning : The goal of this thesis is the development of scalable, low cost synthesis of metal oxide nanostructures based electrodes and to correlate the chemical modifications with their energy conversion performance. Methods in energy conversion in this thesis have focused on two aspects; a potentiometric chemical sensor was used to determine the analytical concentration of some components of the analyte solution such as dopamine, glucose and glutamate molecules.
