  1. 1. Application of Fourier Transforms to time-resolved ambient pressure spectroscopy operando studies of CO oxidation over Pt(111)

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Author : Grigore-Leon Ratiu; [2024]
    Keywords : Physics and Astronomy;

    Abstract : The study of heterogeneous catalysis has important implications in increasing the efficiency of industrial processes and in reducing the emissions of greenhouse gases from sources such as automobiles. A reaction with high industrial relevance is the oxidation of CO on noble metal catalysts. READ MORE

  3. 2. Development and understanding of a model V2O5/anatase TiO2(101) SCR catalyst

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Johanna Paulsson; [2023]
    Keywords : Physics and Astronomy;

    Abstract : A model V2O5/ anatase TiO2(101) SCR catalyst is studied with the purpose of developing and understanding the reaction mechanism through which this catalyst reduces NOx. Several reaction mechanisms have been proposed for this catalyst in the past, but there is still no agreement on which of these describe the reaction the best, if any. READ MORE

  4. 3. Tuning electrolyte-electrode interphases for low-temperature Li-ion batteries

    University essay from Uppsala universitet/Strukturkemi

    Author : Robin Xu; [2023]
    Keywords : Li-ion batteries; Low temperature;

    Abstract : Lithium ion batteries (LIBs) are crucial for modern electronics and electric vehicles (EV). However,their electrochemical performance is facing challenges at low temperatures (e.g ≤ 0 °C) due to reducedLi+ kinetics and increased charge-transfer resistance. READ MORE

  5. 4. Synthesis of glass-ceramic Li2S-P2S5-based electrolyte for solid-state batteries

    University essay from Uppsala universitet/Oorganisk kemi

    Author : Leo Sjörén; [2023]
    Keywords : Solid electrolyte; Battery; sulphide; glass; electolyte; ball milling; ceramic; glass-ceramic; Batteri; elektrolyt; glas; glaskeram; svavel;

    Abstract : In this project, solid sulphur based Li3PS4 electrolytes doped with Li4SiO4 were synthesised using two methods. In method A, a bought β-Li3PS4 electrolyte from Nei Corp was doped with 5 mole per cent Li4SiO4, resulting in a glass-ceramic electrolyte. READ MORE

  6. 5. Interfacial Dynamics at Surface Modified Molecular/Perovskite Solar Cells : How measurements are made to understand solar cell stability

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Benjamin Verbeek; [2023]
    Keywords : perovskite; solar cell; solar; energy; XPS; synchrotron;

    Abstract : Humanity has great energy demands, and must simultaneously combat climate change by curbing anthropogenic greenhouse gas emissions. Perovskite solar cells (PSC) provide a low-carbon energy source, at lower production costs than traditional silicon-based solar cells. PSC's suffer some issues with long-term stability. READ MORE
