Unravelling synergistic effects in bi-metallic catalysts: deceleration of palladium–gold nanoparticle coarsening in the hydrogenation of cinnamaldehyde (2023)
Journal Article
Pinto, J., Weilhard, A., Norman, L. T., Lodge, R. W., Rogers, D. M., Gual, A., …Alves Fernandes, J. (2023). Unravelling synergistic effects in bi-metallic catalysts: deceleration of palladium–gold nanoparticle coarsening in the hydrogenation of cinnamaldehyde. Catalysis Science and Technology, https://doi.org/10.1039/d3cy00289f

In this work, we demonstrate that the synergistic effect of PdAu nanoparticles (NPs) in hydrogenation reactions is not only related to high activity but also to their stability when compared to Pd mono-metallic NPs. To demonstrate this, a series of m...
