“…28 Moreover, the characteristic stretching bands of C=C aromatic and C=C alkane vibrations for poly(EPE)/DLHCs were located at 1488 and 1573 cm À1 , while characteristic peaks of C-S band on the thiophene ring can be exhibited at 934, 846 and 710 cm À1 . 29 The stretching bands of C=N and N-N in pyridazine ring are located at 1656 and 1437 cm À1 , while the C=N stretching appeared at 1650 cm À1 which originated from the pyridine, further demonstrate the successful formation of the binary nanocomposite. 16,30 Figure 5 shows a typical XRD diffraction peaks of poly(BPE)/DLHCs/PtCu and poly(EPE)/DLHCs/PtCu synthesized under same reaction conditions.…”

“…Other intense peaks observed at 1262 and 1052 cm −1 correspond to the C‐O‐C and C‐C‐O stretching bands in ethylenedioxy group of the EDOT on the polymers 28 . Moreover, the characteristic stretching bands of C=C aromatic and C=C alkane vibrations for poly(EPE)/DLHCs were located at 1488 and 1573 cm −1 , while characteristic peaks of C‐S band on the thiophene ring can be exhibited at 934, 846 and 710 cm −1 29 . The stretching bands of C=N and N‐N in pyridazine ring are located at 1656 and 1437 cm −1 , while the C=N stretching appeared at 1650 cm −1 which originated from the pyridine, further demonstrate the successful formation of the binary nanocomposite 16,30 …”

Hybrid 2D‐1D nanostructure of NiO composited with PEDOT : PSS and rGO : Bifunctional electrocatalyst towards methanol oxidation and oxygen evolution reaction

“…The peaks at 1638, 1525, 1197 and 1065 cm −1 are assigned CC alkane stretching, CC aromatic stretching, COC stretching and CCO stretching, respectively. The signature peaks of PEDOT:PSS seen at 834, 672 and 1321 cm −1 correspond to CS stretching of thiophene ring and SO 3 H group of PSS, respectively 48,49 . The FTIR spectrum of NiO nanostructure (Figure S3ii) shows a strong peak at 416 cm −1 related to NiO stretching.…”

“…Moreover, a small hump is observed in diffraction peak of NiPR due to presence of rGO in Figure 2A. 48,49 The FTIR spectrum of NiO nanostructure (Figure S3ii) shows a strong peak at 416 cm À1 related to Ni O stretching. Additionally, the peak observed at 572 cm À1 corresponds to Ni O H stretching vibration.…”

Bioinspired graphene-based metal oxide nanocomposites for photocatalytic and electrochemical performances: an updated review

“…In recent years, a great deal of effort has been dedicated to solving the widespread pollution caused by effluents from urban and agricultural industries, which includes bio recalcitrant and organic pollutants. 283 in the rapid industrialization and continuous progression of newer technologies coupled with poor environmental policies have led to the generation of toxic effluents in huge amounts, which are discarded into natural water bodies. The main components of this chemical discharge from the textile, chemical, petroleum and many other industries are azo dyes.…”
