Project description
Catalyst stability for high hydrogen evolution current
Hydrogen is a potential alternative to fossil fuels. The best way to obtain it is electrolytic water splitting based on renewable energy sources. Hydrogen evolution reaction (HER) electrocatalysts, such as Pt, are the most active but costly and non-resistant over time due to the accumulation of metal nanoparticles on the support. The EU-funded HyCat project proposes solutions to reduce the quantity of noble metal in order to secure catalyst stability by impeding aggregation. The solution will be based on a highly active and stable HER catalyst composed of a nanostructured Cu-Pt porous layer, directly grown onto a Ti current collector by in-situ slow electrodeposition of Pt. This catalyst provides high hydrogen evolution current and long-term stability under operational conditions.
Objective
Hydrogen could replace fossil fuels, and electrolytic water splitting using renewable energy sources is a promising way to obtain it. The most active hydrogen evolution reaction (HER) electrocatalysts to date are platinum group metals (PGM), mainly Pt and its alloys, deposited onto a carbon support. Pt is however costly and the catalysts degrade over time, due to aggregation of metal nanoparticles over the support. Also, no valuable contenders to Pt group metals have been identified for the alkaline HER. To address these issues, we propose to focus again on PGM based catalysts, but with solutions that reduce the amount of noble metal and that ensure catalyst stability by preventing aggregation. In our recently completed ERC project TRANS-NANO, we have prepared a highly active and stable HER catalyst, composed of a nanostructured Cu-Pt porous layer, directly grown onto a Ti current collector by in-situ slow electrodeposition of Pt. This catalyst delivers high hydrogen evolution current and outperforms the benchmark Pt/C in terms of activity at high overpotentials, and solves the most critical issue of Pt/C: its low long-term stability under operational conditions. Our catalyst can achieve the same performances of the Pt/C catalyst, but with a much lower Pt loading. For Ru, the process delivers a Cu-Ru/Ti catalyst with even better performance than the Cu-Pt/Ti system. In this POC project, we will upscale the production of Cu-Pt and Cu-Ru catalysts, starting from large area Ti substrates. Their HER activity will be tested under industrially relevant conditions. Such electrode architecture will enable the fabrication of high-performance alkaline water electrolysers for large-scale applications. Our team is best suited to take this challenge, having a consolidated expertise in developing nanoscale materials and catalysts, and in their exploitation for both oxygen and hydrogen evolution reactions. The proposal envisages a strong collaboration with the industry sector.
