Researchers from the University of Nottingham and University of Birmingham have pioneered a sustainable catalyst using tin microparticles on a nano-textured carbon support for converting CO2 into valuable products. This development offers a pathway for next-generation electrocatalysts. The catalyst's design facilitates electron transfer from the carbon electrode to CO2 molecules, crucial for converting CO2 into formate under an electric potential. The process of electrocatalysis, which utilizes renewable energy sources and water as a hydrogen source, is highlighted as an important alternative to traditional thermal methods reliant on fossil fuels. The catalyst demonstrated exceptional performance, with increasing activity during use, attributed to tin particles breaking down into nanoparticles, enhancing electron transport. The research team's precise control at the nanoscale led to highly selective and stable catalysts for efficient CO2 conversion. This breakthrough could play a significant role in sustainable CO2 conversion and advancing towards achieving net-zero emissions targets.
