Title:  Water oxidation with all-inorganic earth-abundant catalysts



Water oxidation catalysis is one of the biggest challenges chemistry is facing today. The discovery of a fast, robust and readily available catalyst would be key for the realization of artificial photosynthesis, an achievement that could probably solve the energy problem worldwide. Oxygen evolution from water is a complex redox process. It occurs at high oxidation potentials and it involves four electrons. Furthermore, turnover conditions are very demanding. An efficient catalyst able to work at low overpotential for optimized energy conversion will also need to be stable to air, light, water, heat and oxidative deactivation. 

2H2O → O2 +4H+ +4e− E = +1.229−0.059(pH)V vs NHE at 25ºC 

Pure inorganic water oxidation catalysts (WOCs) are a remarkable alternative to typical coordination chemistry candidates, where organic ligands support the metal complex. The presence of organic ligands precludes long-term stability under turnover conditions because of oxidative deactivation. Here we will present our latest results in two different types of promising candidates: 

i) Polyoxometalates (POMs) are a versatile family of inorganic molecular clusters. In these polyanions a transition-metal core can be stabilized by discreet metal-oxide frameworks. Several POMs have been reported as homogeneous water oxidation catalysts (WOCs) in recent years.[1,2,3] However, the actual performance of POMs has been put into question[4,5] and they are the subject of some controversy. Although stable to oxidative deactivation, they exhibit a complex solution equilibria that may yield adventitious cobalt oxides in certain experimental conditions. On the contrary, POMs can also be immobilized onto solid state supports, remaining remarkably active in heterogeneous conditions. 

ii) Transition metal hexacyanometallates (Prussian blues) are stable in a wide pH range, and able to promote water oxidation for days without significant appearance of fatigue, at high turnover frequencies.[6] This family of coordination polymers represents a novel alternative to metal oxide WOCs, while adding the typical advantages of molecule-based materials: well-defined crystal structure, high porosity, low density, flexibility, processability and transparency to visible light.


José Ramón Galán-Mascarós, born in Valencia in 1970, received his education in Chemistry at the University of Valencia (Spain) and Imperial College (London). He received his PhD in 1999 at the University of Valencia with Prof. Eugenio Coronado in the chemistry and physical properties of hybrid organic-inorganic frameworks based on transition metal clusters and coordination polymers.

Between 1999 and 2002 he stayed as post-doctoral fellow at Texas A&M University, College Station, working with Prof. Kim R. Dunbar in the development of molecule-based magnets and single-molecule magnets. In 2002 Dr. Galán-Mascarós got a Ramón y Cajal Fellowship to join the Instituto de Ciencia Molecular (Valencia, Spain), where he worked in multifunctional materials with combination of magnetic and electrical properties. In September 2009 he took a position at the Institute of Chemical Research of Catalonia (ICIQ), where he currently leads a research group devoted to the development of coordination chemistry for applications in Energy and Material Sciences.  In september 2010, he became  ICREA (Catalan Institution of Research and Advanced Studies) Research Professor. JR Galán-Mascarós has received several awards including the Young Chemist Research Award (2002) of the Spanish Royal Society of Chemistry; the Olivier Kahn International Award (2008) of MAGMANet European Network of Excellence; and an ICREA (Catalan Institution of Research and Advanced Studies) Research Professor fellowship (2010). He has also been awarded a European Research Council Starting Independent Researcher Grant (ERC Stg Grant) to develop his project “Building-up Chemical Complexity into Multifunctional Molecule-based Hybrid Materials” (CHEMCOMP).


Research Interests

Our research team is devoted to the development of new molecule-based materials for applications in the fields of renewable energies and multifunctional smart materials. On the former, we are developing efficient and stable redox catalysts from earth abundant metals, with special interest in water oxidation catalysis for the production of solar fuels. On the later, we target the design of novel multifunctional hybrid materials with co-existence of properties of interest (magnetic, catalytic, electrical, optical) with control of the synergy between physical properties through external stimuli in the search for new phenomena.
