We are currently exploring new avenues to the creation of tuneable single atom platforms (SAPs), combining the two fields of single atom catalysts (SACs) and on-surface synthesis (OSS). SACs are materials where a small amount of a catalytically active metals (e.g. Pt, Pd, Co, …) is dispersed onto the surface of a more inert host metal (e.g. Cu, Ag, Au, …) or oxide (e.g. CuOx, …). These materials have revealed promising catalytic activities with the advantage of exploiting very low concentrations of precious metals. However, they exhibit some limitations, as a poor tuneability, clustering, non-uniform distance between the active sites, and diffusion of the single atoms at elevated temperature. Our aim is to develop hybrid nanomaterials where the single metal atoms are stabilized in specifically designed coordination sites of carbon-based polymers obtained via OSS. This approach permits the achievement of catalytically active centers that are equally distributed over the surface and stable in a wide temperature range, due to the atomic precision and robustness of the extended organic template. More importantly, the ease of modification of the organic templates offers unprecedented tuneability prospects for the fine adjustment of the active site functionality.
