Descrizione del progetto
Catalizzatori spin polarizzati per la produzione economica di idrogeno
L’idrogeno è in cima alla lista dell’UE quale combustibile promettente, pulito, economico e a basse emissioni di carbonio e tra le possibili tecnologie per la sua produzione figura l’elettrolisi dell’acqua sfruttando l’energia rinnovabile. Tuttavia, ne è impedita un’ampia diffusione poiché sono necessari metalli del gruppo del platino (MGP) rari e costosi per catalizzare la reazione catodica di evoluzione dell’idrogeno e la reazione anodica di evoluzione dell’ossigeno. Pertanto, lo sviluppo di catalizzatori efficienti privi di MGP è fondamentale per conseguire gli obiettivi di decarbonizzazione dell’UE. Il progetto SpinCat, finanziato dall’UE, creerà una nuova classe di catalizzatori magnetici presenti in abbondanza sulla Terra che, attraverso la polarizzazione dello spin, può triplicare l’attività catalitica verso la reazione di evoluzione dell’ossigeno rispetto ai catalizzatori d’avanguardia, per una produzione economica di idrogeno senza l’uso di MGP.
Obiettivo
For Europe to achieve climate neutrality by 2050, H2 has been identified as one of the priority areas for clean, affordable and secure energy to replace oil and gas, in accordance with the European Green Deal. Water electrolysis using renewable energy is the leading energy storage contender as a clean H2 source to establish a sustainable H2 economy. However, the necessity of using rare and expensive platinum groups metals (PGMs) to catalyse the cathodic hydrogen evolution reaction (HER) and the anodic oxygen evolution reaction (OER) hinders the wide implementation of water electrolysis. Therefore, the development of efficient PGM-free catalysts is of utmost importance for Europe to reach its decarbonization objectives.
SpinCat addresses this need by realizing a new class of magnetic earth-abundant catalysts that, through spin polarization, will boost catalytic activity towards OER by a factor of three as compared to state-of-the-art catalysts. Further enhancements to catalytic activity will be obtained through the use of external magnetic field during catalysis. Through an interplay of experiment and theory, we will design and prepare catalyst materials featuring optimal spin polarization effects, gain fundamental knowledge on the parameters affecting the OER activity of magnetic materials, and develop a general theoretical model for the overall description of the influence of the electron spin in electrocatalysis. The technology will be demonstrated in a magnetically enhanced anion-exchange membrane (AEM) electrolyser prototype, which merges the benefits of both internal and external magnetic effects.
The long-term vision of SpinCat is to establish cost-effective H2 production via reducing the cost of membrane-based electrolyser technology by omitting the need of PGMs. This project will contribute to establishing Europe as the world leader in electrolyser technology for renewable H2 production.
