Rational design concepts of Engineered Ceramics with Integrated catalytically active metal sites For electrochemical Energy conversion – RECIFE

Submission summary

Achieving a sufficient, permanent, emission-free and environmentally friendly energy system is a top priority for the global energy agenda. In these global efforts, material design and electrochemistry play a central role in offering alternative energy solutions. Renewable hydrogen, in particular, produced by electrolysis, is one of the most promising approaches for efficient decarbonization of the energy system. It also represents a safe and sustainable source of energy. The RECIFE project aims to develop and construct a new class of water-splitting electrode materials based on non-noble transition metals (TM) and engineered ceramics by combining material modeling, machine learning and advanced design and characterization concepts. The collaboration between two French and one German institutes, each with complementary expertise, should lead to electrodes that exceed the catalytic activity and durability of conventional products and enable the development of powerful next-generation oxygen evolution reactions (OER) electrolysis catalysts. Particular attention is paid to the design of TM-containing ceramic nanocomposites specially developed for the planned application, which consist of accessible, nano-scale, non-noble, active TM particles dispersed in a ceramic matrix. These nanocomposites must have a catalytically active specific surface as well as an appropriate electrical conductivity and chemical resistance, as required for the OER. The planned RECIFE project combines for the first time (1) the accuracy of first-principles modeling (2) the use of computer data as a source for the prediction of material properties by artificial intelligence (3) an experimental characterization of the structural properties of the synthesized electrode materials based on deep learning algorithms, (4) the experimental synthesis, supported by machine learning and first principle models, and (5) the adaptation of the manufacturing methods to enable up-scaling of electrodes. The modeling work packages are expected to provide important insights into the structure of the ceramic materials at the atomic level, as well as a microscopic insight into the OER mechanisms and the electrochemical processes taking place on the bare and hydrated nanocomposite electrodes. The experimental part of the proposed project focuses on the development of protocols for the synthesis, optimization and design of optimal, transition metal-modified, ceramic nanocomposite electrodes.
