“…The peaks at the 2.8–3.2, 4.25–4.3, and 4.9 ppm regions are attributed to glucose. , The NMR result shows that after the electrocatalyst on the Ta NiFe LDH/NF, there are no peaks corresponding to glucose, which indicates glucose converted to GRA and GNA. , Furthermore, the peak at around 8.5 ppm in the H NMR spectrum corresponded to the formation of the −COOH group. In addition, the 2.28, 2.76, and 2.38 ppm peaks indicate the −OH groups, which confirm the formation of GRA and GNA after electrocatalyst on the Ta NiFe LDH/NF electrode. , However, FTIR and NMR analysis cannot detect the entire oxidation of glucose into GNA and GRA. Additionally, because the functional group compositions of GNA and GRA are quite similar, the formation of these two compounds cannot be explained only by their FTIR and NMR spectra.…”
