Solar energy-driven hydrogen production KU Leuven
Nearly all current hydrogen generating processes use fossil fuels that lead to CO2 and GHG emissions. Towards a de-fossilization of its production, a distinction is now made between non-fossil-based 'green H2' with very low CO2 emission, 'gray H2' from hydrocarbons with CO2 emission, and 'blue H2' where the carbon emission is captured and possibly utilized. The thermal fossil fuel-based hydrogen production technology includes steam reforming, ...
Producing hydrogen by catalytic steam reforming of methanol using non-noble metal catalysts KU Leuven
Current energy systems have a significant environmental impact and contribute to the climate change. The future energy systems must call upon clean and renewable sources, capable of producing energy with low CO2 emission, hence partly decarbonizing the energy sector. Producing H2 by catalytic steam reforming of methanol (CSRM) is gaining interest for its specific applications in fuel cells, in a decentralized H2 production, or to locally boost ...
Water splitting by MnFe2O4/Na2CO3 reversible redox reactions KU Leuven
Future energy systems must call upon clean and renewable sources capable of reducing associated CO2 emissions. The present research opens new perspectives for renewable energy-based hydrogen production by water splitting using metal oxide oxidation/reduction reactants. An earlier multicriteria assessment defined top priorities, with MnFe2O4/Na2CO3/H2O and Mn3O4/MnO/NaMnO2/H2O multistep redox cycles having the highest potential. The latter redox ...
Adsorption of acid fuchsine dye from wastewater by Mg-ferrite particles KU Leuven
Adsorption is a widely applied waste water treatment technology, especially for removing micro-pollutants and dyes of industrial effluents. Over the past decade, adsorbing metal oxide micron- and nano-particles have been successfully developed and investigated as adsorbents. In the present research, Mg-ferrite adsorbent particles were synthesized and their properties were fully determined. The pore volume is 0.139 cm3/g. The BET analysis reveals ...
