Reconstructing a hydrogen-driven microbial metabolic network in Opalinus Clay rock

Rizlan Bernier-Latmani, Alexandre Bagnoud

The Opalinus Clay formation will host geological nuclear waste repositories in Switzerland. It is expected that gas pressure will build-up due to hydrogen production from steel corrosion, jeopardizing the integrity of the engineered barriers. In an in situ ...

Influence of anodization time on the surface modifications on alpha-Fe2O3 photoanode upon anodization

Artur Braun, Yelin Hu

In searching for a suitable semiconductor material for hydrogen production via photoelectrochemical water splitting, alpha-Fe2O3 received significant attention as a promising photoanode due to its band gap (similar to 2.1 eV), good stability, low cost, and ...

A membrane-less electrolyzer for hydrogen production across the pH scale

Demetri Psaltis, Miguel Antonio Modestino, Seyyed Mohammad Hosseini Hashemi

The development of deployable water-splitting devices is hindered by the cost of electricity and the lack of stable ion conducting membranes that can operate across the pH scale, impose low ionic resistances and avoid product mixing. The membrane-less appr ...

Royal Society of Chemistry2015

Providing energy for a population projected to reach 9 billion people within the middle of this century is one of the most pressing societal issues. Burning fossil fuels at a rate and scale that satisfy our near-term demand will irreversibly damage the liv ...

A nanoporous molybdenum carbide nanowire as an electrocatalyst for hydrogen evolution reaction

Hubert Girault, Xile Hu, Micheal Diarmaid Scanlon

A highly active and stable electrochemical catalyst of nanoporous molybdenum carbide nanowires (np-Mo2C NWs) has been developed for hydrogen evolution reaction (HER). The np-Mo2C NWs were synthesized simply by pyrolysis of a MoOx,/amine hybrid precursor wi ...

Hydrogen Production by Selective Dehydrogenation of HCOOH Catalyzed by Ru-Biaryl Sulfonated Phosphines in Aqueous Solution

Gabor Laurenczy, Katerina Stefania Sordakis

The selective dehydrogenation of aqueous solutions of HCOOH/HCOONa to H2 and CO2 gas mixtures has been investigated using RuCl3·3H2O as a homogeneous catalyst precursor in the presence of di␣erent monoaryl-biaryl or alkyl-biaryl phosphines and aryl diphosp ...
