Enhanced Solar-to-Fuel Efficiency of Ceria-Based Thermochemical Cycles via Integrated Electrochemical Oxygen Pumping

Sophia Haussener, Clemens Gregor Suter, Meng Lin

The solar thermochemical cycle based on ceria is a promising route for renewable fuel production. The solar-to-fuel efficiency of a thermochemical reactor is highly dependent on the oxygen removal during the reduction step. Conventional nitrogen sweeping ( ...

High-valence metals improve oxygen evolution reaction performance by modulating 3dmetal oxidation cycle energetics

Likai Zheng, Yang Li, Yelin Hu, Jun Li, Ye Zhang, Ziyun Wang, Bo Zhang, Zhen Cao

Multimetal oxyhydroxides have recently been reported that outperform noble metal catalysts for oxygen evolution reaction (OER). In such 3d-metal-based catalysts, the oxidation cycle of 3dmetals has been posited to act as the OER thermodynamic-limiting proc ...

Understanding Digestive Ripening of Ligand-Stabilized, Charged Metal Nanoparticles

Hubert Girault, Pekka Eero Peljo

Most syntheses of thiolate-protected metal nanoparticles (NPs) include a thermochemical step in which the as-prepared, polydisperse NPs are transformed to a narrower size distribution in a poorly understood process known as digestive ripening (DR). Previou ...

RedOx Stability of Anode Supported Solid Oxide Fuel Cells

Antonin Faes

The weakness of nickel-based solid oxide fuel cell anodes is their low ability to withstand re-oxidation at working temperature, especially for the anode-supported cell design. The volume expansion coming along with nickel (Ni) oxidation induces stresses i ...

Optimal technologies for the thermochemical production of Synthetic Natural Gas (SNG) from lignocellulosic biomass

François Maréchal, Martin Gassner

The conversion of lignocellulosic biomass to methane is a promising way to distribute a renewable resource as a versatile energy vector in an existing grid. Potentially more efficient than the production of liquid fuels, it can be used as Synthetic Natural ...

Thermo-economic Evaluation of the Thermochemical Production of Liquid Fuels from Biomass

François Maréchal, Martin Gassner, Laurence Tock

Different technological alternatives for the thermochemical production of liquid fuels from lignocellulosic biomass are systematically analyzed and optimized based on thermo-environomic models. The competitiveness of the production of Fischer-Tropsch fuel ...

Process Design Methodology for Thermochemical Production of Fuels from Biomass

Martin Gassner

Biomass is a renewable, yet scarce resource since land is limited. This thesis addresses the question how to efficiently convert the available lignocellulosic biomass and biomass wastes to fuel and other useful energy services. In particular, it presents a ...
