WebThe mid-IR spectra of the samples were recorded before and after irradiation at T:15 K. Additional spectra were recorded during warming of the samples. The spectral resolution employed was4cm˝1 on a Mattson FTIR spectrometer. 3. Discussion The IR spectra of a 1:1:2 12CO 2:H 2 O:NH 3 film at 15 K before and after irradiation are repro- Web(a) XRD and (b) FTIR spectra of g-C 3 N 4 samples prepared by co-polymerization of melamine and urea precursors. The functional groups were elucidated through FTIR analysis. Fig. 1 b shows the FTIR spectra of all samples, where the bands at 805–880 cm −1 can be assigned to the out-of-plane breathing mode of N H and the breathing mode of the ...
