One step process for generating ultra pure alloy nanoparticle catalysts webinar

A webinar on the One step process for generating ultra pure alloy nanoparticle catalysts from Dr. Vicky Broadley, Nikalyte Ltd. Electrochemical splitting of water offers a zero-carbon method for converting renewable energy to hydrogen. Economical production requires electrocatalysts that reduce the overpotentials for the hydrogen and oxygen evolution reactions (HER/OER) to avoid energy wastage and lower operating costs. The best performing OER catalysts are based on iridium, whose scarcity and cost limits the large-scale deployment of this technology. There is thus a pressing need for the development of low-cost electrocatalysts that use lower loadings of these components or fully replace them with earth-abundant elements. High-entropy alloy nanoparticles (HEA-NPs), that consist of 5 or more component elements, are a promising class of electrocatalyst materials, that provide a wide parameter space for performance tuning and the potential for each constituent element to perform complementary roles. Plasma vapour deposition (pvd) offers many advantages over other nanoparticle synthesis techniques, due to superior reproducibility and lower environmental impact. In this Webinar Vicky will present a one step pvd process for generating complex alloy nananoparticles and will share data on the OER performance of high entropy alloy nanoparticle catalysts.
