Cuprous oxide-Shewanella mediated photolytic hydrogen evolution

Michael Graetzel, Christos Comninellis, Kevin Sivula, Nikolaos Vlachopoulos, Meng Xia, Linfeng Pan, Michele Morgante

However, its green production process is expensive, involving water electrolysis, which requires a significant amount of energy. New technologies have been developed to decrease the cost associated with water electrolysis, such as using microbial electroly ...

Efficient Electrochemical Production of Peroxodicarbonate Applying DIACHEM (R) Diamond Electrodes

Christos Comninellis

The electrochemical synthesis of peroxodicarbonate was performed on boron-doped DIACHEM((R)) diamond anodes (BDD). The influence of various parameters was studied and promising conditions were determined in an undivided cell design by CONDIAS GmbH. The bes ...

Scale-up of phosphate remobilization from sewage sludge in a microbial fuel cell

Christos Comninellis, Fabian Fischer, Alain-François Grogg, Marc Sugnaux, Thomas Egli, Géraldine Zufferey

Phosphate remobilization from digested sewage sludge containing iron phosphate was scaled-up in a microbial fuel cell (MFC). A 3 litre triple chambered MFC was constructed. This reactor was operated as a microbial fuel cell and later as a microbial electro ...

Modeling of Sustainable Base Production by Microbial Electrolysis Cell

Christos Comninellis, Fabian Fischer, Marc Sugnaux, Maxime Blatter

A predictive model for the microbial/electrochemical base formation from wastewater was established and compared to experimental conditions within a microbial electrolysis cell. A Na2SO4/K2SO4 anolyte showed that model prediction matched experimental resul ...

Fixed Energy X-ray Absorption Voltammetry and Extended X-ray Absorption fine Structure of Ag nanoparticle electrodes

Christos Comninellis

FEXRAV (Fixed Energy X-ray Absorption Voltammetry) has been recently introduced as a powerful tool in electrochemistry. It consists in measuring the X-ray absorption coefficient at a fixed X-ray energy while the electrochemical potential of the material un ...

Highly-Ordered Magneli Ti4O7 Nanotube Arrays as Effective Anodic Material for Electro-oxidation

Christos Comninellis, Caroline Miles

Pure Magneli Ti4O7 nanotube arrays (NTA) were successfully fabricated by reducing TiO2 NTA with hydrogen at 850 degrees C for 30 minutes. The microstructure, composition and electrochemical behavior of the prepared Ti4O7 NTA were characterized by means of ...

Renewable hydrogen generation from a dual-circuit redox flow battery

Hubert Girault, Christos Comninellis, Xile Hu, Heron Vrubel, Véronique Amstutz, Kathryn Ellen Toghill, Francis Powlesland

Redox flow batteries (RFBs) are particularly well suited for storing the intermittent excess supply of renewable electricity; so-called “junk” electricity. Conventional RFBs are charged and discharged electrochemically, with electricity stored as chemical ...
