  1. 1. Redox Materials in Hydrogen Production : Investigation of state-of-the-art redox materials in thermochemical cycles for hydrogen production via solar energy

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Saga Berneryd; [2023]
    Nyckelord :;

    Sammanfattning : This bachelor thesis work has investigated different redox materials in 2-step thermochemical water splitting processes for solar-driven hydrogen production. Materials have been mapped out by their results from experimental activity and by the conditions the tests were conducted in. LÄS MER

  3. 2. Phase and Interface Design in Potential Earth-Abundant Multi-Component Photocatalysts

    L3-uppsats, Lunds universitet/Kemiska institutionen

    Författare :David Llorens Rauret; [2022]
    Nyckelord :Facet control; in-situ TEM; nanoparticle heterostructures; phase transformation; transition metal phosphides; inorganic nanomaterials; Chemistry;

    Sammanfattning : Transition metal phosphides are low-cost, earth-abundant semiconductors with promising properties for photocatalysis, including water-splitting. When combined with other semiconductors or noble metals in nanoparticles, their photocatalytic performance can be drastically enhanced. LÄS MER

  4. 3. Demonstration and investigation of hydrogen production by water splitting through plasmon assisted photocatalysis involving a cobalt catalyst.

    Magister-uppsats, Uppsala universitet/Fysikalisk kemi

    Författare :Amal Mendalz; [2022]
    Nyckelord :;

    Sammanfattning : Plasmonic heterostructures are of great interest within the industry and in the academia owing to theirapplications in photovoltaics and photocatalysis. The Localised surface plasmon resonance (LSPR) leading to an intensification of the electromagnetic (EM) field on the surface of the plasmonic nanoparticles results in an efficient absorption of light over miniscule thickness of the material.

  5. 4. Tuning the composition of metallic nanoparticles for catalytic applications

    Master-uppsats, KTH/Kemi

    Författare :Anthony Ropp; [2021]
    Nyckelord :catalysis; nanoparticles; frustrated Lewis pairs; synthesis; core-shell;

    Sammanfattning : Industries’ interest in nanomaterials is tremendous and catalysis is one of their applications. Catalysts allow reactions to occur under milder conditions, avoiding committing excessive heat or pressure to foster reactions. LÄS MER

  7. 5. Artificial photosynthesis - 4-Aminobenzoic acids effect on charge transfer in a photo catalytic system

    Kandidat-uppsats, Uppsala universitet/Materialteori

    Författare :Simon Moberg; [2019]
    Nyckelord :artificial photosynthesis; aminobenzoic acid; charge transfer; plasmon; induced; plasmon induced; nanostructure; nanostructures; solar energy; nano particles; nano particle; artificiell fotosyntes; aminobensoesyra; laddningsöverföring; plasmon; inducerad; plasmoninducerad; nanostruktur; nanostrukturer; solenergi; nanopartiklar; nanopartikel;

    Sammanfattning : Artificial photosynthesis is used to harvest solar energy and store it in the form of chemical bonds. The system of interest in this study does this by splitting water into hydrogen and oxygen gas through a plasmon assisted process, collective oscillations from free electron gas. LÄS MER
