Switzerland To Develop New Efficient And Cheap Nano-water Electrolysis Catalyst
Dec 12, 2017

The use of solar and wind power to generate electricity and the production of hydrogen through electrolysis of water with the resulting electricity is an important technological means of storing renewable energy. There are two types of catalysts currently used to accelerate the electrolysis of water reactions, one that is highly catalytically efficient but requires the use of precious metal iridium materials, resulting in high costs and the other being less expensive but not highly catalytically inefficient.

    The Swiss Institute of Paul Schorell (PSI) has recently succeeded in developing an efficient nanocatalyst that can be used for the electrolysis of hydrogen to obtain hydrogen, which is inexpensive and does not require the use of precious metals. The new catalyst is barium, strontium, cobalt, iron perovskite compounds. The research team first developed a new process that controls the proper conditions in the "flame spray" facility of the company to combine barium, strontium, cobalt and iron atoms in the flame to form tiny nanoparticles of the desired structure, allowing the catalyst With as large a surface area as possible to form more "activation centers" that accelerate the cleavage of water molecules. By adjusting the proportion of oxygen in the material, a series of catalyst materials can be formed. Successful commissioning of this new catalyst in the pilot plant of the state-of-the-art new energy research infrastructure "Energy Systems Integration Platform" in Switzerland is comparable in performance to traditional iridium oxide catalysts, but at a low cost and with a very easy production process Achieve large-scale production.

    The institute is working with U.S. electrolyzed water equipment manufacturers to further validate and test its performance and reliability in practically used industrial equipment.
