Here we report a copper-based catalyst with isolated active copper sites for the hydrogenation of CO2 to methanol. It is revealed that the single-atom Cu–Zr catalyst with Cu1–O3 units contributes solely to methanol synthesis around 180 °C, while the presence of small copper clusters or ...
here we investigate the metal-supported single atoms to enable CO2hydrogenation. We find a copper-supported iron-single-atom catalyst producing a high-rate methane.
Copper-based catalysts are traditionally very effective for the hydrogenation of CO2 to methanol, although control over the active site has remained elusive. Here, the authors design a Cu1/ZrO2 single-atom catalyst featuring a Cu1–O3 site responsible for a remarkable performance at 180?°C. DOI...
(POPs) functionalized with a reticular aminopyridine group were purposely fabricated to mimic the homogeneous ligand environment for chelating the Ir single-atom active center, and this quasi-homogeneous Ir1/POP catalyst manifests high efficiency for hydrogenation of CO2 to formate under mild conditions...

Single-atom catalysts (SACs) have atomically dispersed catalytic sites with uniform geometric and electronic structures that regulate the surface local charge distribution of the catalyst, providing abundant highly active catalytic sites3. Thus, SACs with isolated single atoms (i-SAs) have garnered sign...
