The researchers found that the metal support interaction (MSI) drove the restructuring of Pd/In2O3 catalysts into Pd–In alloy sites during CO₂ electroreduction. This restructuring led to a significant improvement in the catalyst's performance and stability.
Can Catalyst Design be Optimized?
The team observed that the Pd–In alloy sites exhibited a higher activity and selectivity towards formic acid production. The researchers attributed this to the unique electronic properties of the alloy sites, which facilitated the adsorption and reduction of CO₂.
To further improve the catalyst's performance, the researchers investigated the effects of different catalyst compositions and structures. They found that by optimizing the Pd/In2O3 ratio and the catalyst's surface morphology, they could enhance the catalyst's activity and stability.
The study's findings have significant implications for the development of efficient CO₂ conversion technologies. By designing dynamic catalyst interfaces, researchers can create more effective catalysts for converting CO₂ into valuable chemicals.
