Chaotropic Agents Boosting the Performance of Photo-ionic Cells

Hubert Girault, Astrid Johana Olaya Avendano, Pekka Eero Peljo, Manuel Alejandro Méndez Agudelo, Heron Vrubel, Jelissa Risse, Romain Bourdon

Photo-ionic cells are a simple and scalable concept for direct solar energy storage, where the redox fuels produced by the photoreaction are separated in different phases to prevent recombination. The presence of chaotropic agents such as urea, that break ...

Electrochemistry in Supercritical Fluids: A Mini Review

Manuel Alejandro Méndez Agudelo, Kathryn Ellen Toghill, Patrick Voyame

A brief overview of the literature relating to electrochemical studies and processes undertaken in supercritical fluids is presented. This review mostly concerns carbon dioxide and hydrofluorocarbons, given the accessibility of their supercritical states, ...

Photo-Ionic Cells: Two Solutions to Store Solar Energy and Generate Electricity on Demand

Hubert Girault, Pekka Eero Peljo, Manuel Alejandro Méndez Agudelo, Heron Vrubel, Micheal Diarmaid Scanlon

A solar energy conversion concept based on the photo-induced separation of a pair of redox species in a biphasic liquid cell is presented. The redox pair is subsequently discharged in an electrochemical flow cell to generate electricity. To illustrate this ...

Gold Metal Liquid-Like Droplets

Hubert Girault, Pierre-François Marie Brevet, Manuel Alejandro Méndez Agudelo, Heron Vrubel, Micheal Diarmaid Scanlon, Dmitry Momotenko, Evgeny Smirnov

Simple methods to self-assemble coatings and films encompassing nanoparticles are highly desirable in many practical scenarios, yet scarcely any examples of simple, robust approaches to coat macroscopic droplets with continuous, thick (multilayer), reflect ...

Photoreduction of CO2 Using [Ru(bpy)2(CO)L]n+ Catalysts in Biphasic Solution/Supercritical CO2 Systems

Hubert Girault, Manuel Alejandro Méndez Agudelo, Kathryn Ellen Toghill, Patrick Voyame

The photosensitized reduction of carbon dioxide by the molecular catalyst [Ru(bpy)2(CO)L] is studied in a biphasic liquid-condensed gas system. Increasing pressure is shown to enhance the initial production rate and turnover number of the catalyst before d ...

Biphasic water splitting by osmocene

Hubert Girault, Xile Hu, Astrid Johana Olaya Avendano, Anne-Clémence Corminboeuf, 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 ...

Interactions and Reactivity at Liquid-Liquid Interfaces : A Bio-Inspired System

Manuel Alejandro Méndez Agudelo

The interface between two immiscible electrolyte solutions (ITIES) provides a well-defined platform for fundamental studies of adsorption processes and molecular reactivity in general. Two bio-inspired systems are considered in the present work: adsorbed p ...

Artificial Photosynthesis at Soft Interfaces

Hubert Girault, Astrid Johana Olaya Avendano, 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, ...

Melittin Adsorption and Lipid Monolayer Disruption at Liquid-Liquid Interfaces

Hubert Girault, Manuel Alejandro Méndez Agudelo, Yu Lu, Zahra Nazemi

Melittin, a membrane-active peptide with antimicrobial activity, was investigated at the interface formed between two immiscible electrolyte solutions (ITIES) supported on a metallic electrode. Ion-transfer voltammetry showed well-defined semi-reversible t ...
