Photoinduced Biphasic Hydrogen Evolution: Decamethylosmocene as a Light-Driven Electron Donor

Hubert Girault, Astrid Johana Olaya Avendano, Heron Vrubel, Micheal Diarmaid Scanlon, Peiyu Ge, Imren Hatay

Excitation of the weak electron donor decamethylosmocene on illumination with white light produces an excited-state species capable of reducing organically solubilized protons under biphasic conditions. Insight into the mechanism and kinetics of light-driv ...

Biphasic water splitting by osmocene

Hubert Girault, Xile Hu, Manuel Alejandro Méndez Agudelo, Heron Vrubel, Peiyu Ge, Imren Hatay

The photochemical reactivity of osmocene in a biphasic water-organic solvent system has been investigated to probe its water splitting properties. The photoreduction of aqueous protons to hydrogen under anaerobic conditions induced by osmocene dissolved in ...

Hydrogen evolution at polarised liquid/liquid interfaces catalyzed by molybdenum disulfide

Hubert Girault, Xile Hu, Heron Vrubel, Peiyu Ge, Imren Hatay

Molybdenum disulfide microparticles in suspension in an aqueous acidic solution adsorb at the interface with an organic electrolyte solution containing the reducing agent, decamethylferrocene, to catalyse hydrogen evolution. This catalytic process has been ...

Artificial Photosynthesis at Soft Interfaces

Hubert Girault, Fernando Cortes Salazar, Manuel Alejandro Méndez Agudelo, Peiyu Ge, Haiqiang Deng, Imren Hatay, Patrick Voyame, Zahra Nazemi

The concept of artificial photosynthesis at a polarised liquid membrane is presented. It includes two photosystems, one at each interface for the hydrogen and oxygen evolution respectively. Both reactions involve proton coupled electron transfer reactions, ...

Oxygen and proton reduction by decamethylferrocene in non-aqueous acidic media

Hubert Girault, Manuel Alejandro Méndez Agudelo, Bin Su, Peiyu Ge, Imren Hatay, Zdenek Samec

Experimental studies and density functional theory (DFT) computations suggest that oxygen and proton reduction by decamethylferrocene (DMFc) in 1,2-dichloroethane involves protonated DMFc, DMFcH+, as an active intermediate species, producing hydrogen perox ...

Oxygen reduction by decamethylferrocene at liquid/liquid interfaces catalyzed by dodecylaniline

Hubert Girault, Manuel Alejandro Méndez Agudelo, Bin Su, Raheleh Partovi Nia, Imren Hatay, Zdenek Samec

Molecular oxygen (O2) reduction by decamethylferrocene (DMFc) was investigated at a polarized water/ 1,2-dichloroethane (DCE) interface. Electrochemical results point to a mechanism similar to the EC type reaction at the conventional electrode/solution int ...

Oxygen reduction catalyzed by a fluorinated tetraphenylporphyrin free base at liquid/liquid interfaces

Hubert Girault, Manuel Alejandro Méndez Agudelo, Bin Su, Imren Hatay, Zdenek Samec

The diprotonated form of a fluorinated free base porphyrin, namely 5-(p-aminophenyl)-10,15,20-tris(pentafluorophenyl)porphyrin (H(2)FAP), can catalyze the reduction of oxygen by a weak electron donor, namely ferrocene (Fc). At a water/1,2-dichloroethane in ...

Hydrogen Evolution at Liquid–Liquid Interfaces

Hubert Girault, Xile Hu, Heron Vrubel, Bin Su, Raheleh Partovi Nia, Imren Hatay

Blowing bubbles: Hydrogen evolution by proton reduction with [(C5Me5)2Fe] occurs at a soft interface between water and 1,2-dichloroethane (DCE). The reaction proceeds by proton transfer assisted by [(C5Me5)2Fe] across the water–DCE interface with subsequen ...
