Fig. 3: Structural characterizations of Ag–AgMOM.

a XRD pattern of Ag–AgMOM, Pawley refinement of porphyrin based MOM from 5° to 25° and the standard pattern of Ag (JCPDS No. 65-2871) from 5° to 80°. b DFT optimized crystal model of porphyrin based MOM in composites. c Raman spectra of Ag–AgMOM, Ag-CuMOM, TCPP and polyvinylpyrrolidone (PVP) taken under the excitation of a 520 nm laser, and DFT calculated Raman spectra of TCPP and PVP (bottom figure). d Normalized X-ray absorption near-edge structure (XANES) spectra at Ag K-edge for the Ag–AgMOM sample and Ag foil. e Fourier transform of k2-weighted extended X-ray absorption fine structure (EXAFS) spectrum (not phase corrected) and best fitting for the Ag–AgMOM sample. f Schematic illustration of the model of a AgNP chemically linked with MOM and pristine interface (few PVP at the interface).
