In the cu 2p region (fig. 5 e), cu 2p 3 2 and cu 2p 1 2 signals were observed along with shake up satellite peaks which is a definitive evidence of the presence of cu 2 species [30]. however, the intensity ratio between the cu 2p 3 2 signal and its adjacent satellite was lower than expected if there was exclusively cu 2 (2.5) [ 31 ] and implied the coexistence of cu species.
The cu 2p 3 2 core level of the samples presented the typical doublet of cu 2 , with the cu 2p 3 2 levels at 934.52 and 954.27 ev (Δ = 19,75), respectively, a weak shake up and a shoulder at ca. 932.58 ev characteristic of cu , indicating that the copper oxidation state is mostly 2 . however, some cu(i) is also present.

Single atom catalysts are often considered as the ultimate design principle for supported catalysts, due to their unique geometric and electronic properties and their highly efficient use of precious materials. here, we report a single atom catalyst, cu uio 66, prepared by a covalent attachment of cu atoms to the defect sites at the zirconium oxide clusters of the metal–organic framework. Uio 66 cu ii in its hydrated form has an x band continuous wave (cw) epr spectrum (figure 5b), with axial (within the resolution of the experiment) spin hamiltonian parameters [g x,y = 2.074, g z = 2.320, a z(cu) = 480 mhz], typical of isolated cu(ii) ions with a d x 2 –y 2 or d xy ground state and consistent with water coordinated in the xy plane; the latter is confirmed by hyscore.

It can be seen that the cu % value in 30 ccu a b catalysts exhibits a volcano trend with increasing the cu ce ratio, and the 30 ccu 3 7 catalyst has the highest cu % value (16.3%). it is well known that the redox cycle of cu 2 ce 3 ↔ cu ce 4 are abundant in contact interface of copper and cerium [ 42 ], thus, the cu % in the catalyst can be a judge for the strength of cu–ce. Photocatalytic reduction of co2 to value added fuels is a promising route to reduce global warming and enhance energy supply. however, poor selectivity and low efficiency of catalysts are usually the limiting factor of their applicability. herein, a photoinduction method was developed to achieve the formation of cu single atoms on a uio 66 nh2 support (cu sas uio 66 nh2) that could.
