Green hydrogen production using Shewanella oneidensis MR-1 bioanode and cuprous oxide-based photocathode
In recent years, many efforts have been made to find alternative renewable energy sources that can ideally replace the use of fossil fuels in all aspects. One of the new emerging energy technologies is the bioelectrochemical system, of which two types are ...
EPFL2024Using Complex Hydrides for Hydrogen Storage and Direct Borohydride Fuel Cells for Electricity Production
Hydrogen storage and utilization are the technologies to achieve carbon-neutral energy systems with renewable energy sources. Among the various materials that have been investigated, complex hydrides are a material exhibiting high gravimetric hydrogen dens ...
EPFL2023Solid-state synthesis of CdFe2O4 binary catalyst for potential application in renewable hydrogen fuel generation
Michael Graetzel, Shaik Mohammed Zakeeruddin
Clean energy is highly needed at this time when the energy requirements are rapidly increasing. The observed increasing energy requirement are largely due to continued industrialization and global population explosion. The current means of energy source is ...
NATURE PORTFOLIO2022Rhodanian Neighborhoods in Transition: Towards an Integrative Strategy Facilitating Decision-Making for New Sustainable Fluvio-Neighborhoods
Martine Laprise, Sara Sonia Formery Regazzoni
In the changing history of city-river relationships, cities are today questioning strategies for “reconciliation”. Thus, rather degraded sites like riverside brownfields represent an important potential for the creation of new sustainable fluvio-neighborho ...
2022Particle Size Effects in Ru/CNF Catalysts during Supercritical Water Gasification of Glycerol
Oliver Kröcher, Frédéric Vogel, David Baudouin, Ayush Agarwal
Ru/CNF catalysts of different Ru nanoparticle (NP) sizes (0.9-2.7 nm) were assessed for their performance in continuous supercritical water gasification (SCWG) of glycerol. A structure sensitivity of Ru was demonstrated, with high initial turnover frequenc ...
2022Boosting hydrogen production via urea electrolysis on an amorphous nickel phosphide/graphene hybrid structure
Paul Joseph Dyson, Zhaofu Fei, Lu Chen, Yun Tong
Overall urea electrolysis has favorable thermodynamic properties and can complement traditional water splitting by simultaneously purifying urea-rich waste streams. However, the kinetics of the reaction is slow and more efficient catalysts are required. In ...
SPRINGER2021Switchable wetting of oxygen-evolving oxide catalysts
Vasiliki Tileli, Tzu-Hsien Shen
The surface wettability of catalysts is typically controlled via surface treatments that promote catalytic performance. Here we report on potential-regulated hydrophobicity/hydrophilicity at cobalt-based oxide interfaces with an alkaline solution. The swit ...
NATURE PORTFOLIO2021Spectroelectrochemical and Chemical Evidence of Surface Passivation at Zinc Ferrite (ZnFe 2 O 4 ) Photoanodes for Solar Water Oxidation
Kevin Sivula, Mounir Driss Mensi, Liang Yao, Nestor Guijarro Carratala, Dan Ren, Yongpeng Liu, Meng Xia
Recent advances in low‐cost manufacturing as well as in bulk/interface engineering have positioned zinc ferrite (ZnFe2O4, ZFO) in the spotlight as a candidate material for solar water oxidation. However, the severe recombination at the reactive interface r ...
2021CO2 Hydrogenation over Unsupported Fe-Co Nanoalloy Catalysts
Andreas Züttel, Marco Calizzi, Kun Zhao, Robin Tobias Andreas Mutschler, Nicola Patelli
The thermo-catalytic synthesis of hydrocarbons from CO2 and H2 is of great interest for the conversion of CO2 into valuable chemicals and fuels. In this work, we aim to contribute to the fundamental understanding of the effect of alloying on the reaction y ...
