Fig. 6. The local coordination analysis of C-SACs with metal-metal interactions.

(A) Mo K-edge FT-EXAFS and WT-EXAFS spectra of W₁Mo₁-NG and the references. Reproduced with permission from the American Association for the Advancement of Science (76). (B) CO-DRIFTS chemisorption spectra of correlated Ni-Cu catalysts. The CO chemisorption on Cu sites was weakened with the increase of Ni concentration, demonstrating the strong Ni-Cu interaction.
