  4. 2. Water splitting by heterogeneous catalysis

    Author : Henrik Svengren; Mats Johnsson; Tomas Edvinsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Faradaic efficiency; electrocatalysis; electrolysis; water oxidation; hydrogen reduction; H2; O2; mass spectrometry; Inorganic Chemistry; oorganisk kemi;

    Abstract : A sustainable solution for meeting the energy demands at our planet is by utilizing wind-, solar-, wave-, thermal-, biomass- and hydroelectric power. These renewable and CO2 emission-free energy sources are highly variable in terms of spatial and temporal availability over the Earth, introducing the need for an appropriate method of storing and carrying energy.
