Electrochemical Detection of 4-Nitrophenol Using a Novel SrTiO3/Ag/rGO Composite

“…Peaks around 151, 431, 873, and 1060 cm –1 are categorized as TO 3 , LO 3 , LO 4 , and A 2 g degrees of order–disorder, respectively. − Furthermore, the peaks appeared at 151 cm –1 as well as 431 cm –1 are ascribed to first-order modes, whereas the peaks at 873 and 1060 cm –1 have been attributed to second-order modes. For the SrTiO 3 /rGO and SrTiO 3 /Ag/rGO composites, two additional peaks appeared at 1359 and 1556 cm –1 corresponding to the D band and G band arising due to in-plane sp 3 defects and sp 2 domine in carbon, respectively. , The 431 and 873 cm –1 peaks slightly changed to 375 and 759 cm –1 , respectively, which could be attributed to the interaction between rGO and SrTiO 3 . The coexistence of main Raman peaks of both SrTiO 3 and rGO, as found in SrTiO 3 /rGO and SrTiO 3 /Ag/rGO composites, further confirms the composite formation.…”

“…Peaks corresponding to STO are observed at approximately 290 cm À1 and 630 cm À1 , consistent with its crystal structure. 51,52 Raman spectra of PANI and GQD are provided in Fig. S6a and b (ESI †).…”

Electrochemical detection of Pb(ii) and Cd(ii) using bismuth ferrite nanoparticle modified carbon paste electrodes

“…26 In recent years, chemically modified electrodes have been used strategically to improve the conductivity, selectivity, sensitivity, stability and surface area of the working electrode. 21,[27][28][29] Carbon paste electrodes (CPEs) have recently attracted a lot of attention due to their benefits such as low background current, easy preparation, quick surface renewal and bulk modification capability. 30 Chemically modified CPEs have been used in stripping analyses to improve electrochemical responses because of these advantages.…”
