A comparison of the TEM images presents g-C3N4 with three different sizes along with their respective structural and morphological features. After applying a potential of -1.5, -3 and -4.5 V for 3 hours, g-C3N4 QDs with an average size of 2.5, 4.1 and 8.7 nm are obtained, respectively, as seen in Figure ), b) and c). Since an increase in the size of the Quantum Dots is revealed as we increase the applied electric field, this could be attributed to the faster dissolution precipitation process, although the counterions in the IL prevent rapid reorganisation due to agglomeration, similar to steric stabilization. Consequently, the dot-like morphology indicates the formation of QDs of various sizes, which have similar size distributions of 3-8 nm when synthesized through melamine from other methods such as hydrothermal, chemical oxidation and solid phase synthesis. A comparison of g-C3N4 QDs of varying sizes is shown in Figure . The weak van der Waals forces stacked the graphitic planes, resulting in the organization of the tri-s-triazine unit, leading to the compression of aromatic planes. The most distinguishable diffraction peak appears at 25.2°, corresponding to the crystal plane (002). The d-spacing due to this plane is 3.53 Å, resembling the interlayer stacking in the graphitic peak, and is corroborated by the crystalline graphite (0.35 nm). Here, the packing density is higher as a consequence of ππ stacking or van der Waals interaction in the adjacent layers due to carbon and nitrogen interaction increasing the thermal and chemical stabilities of g-C3N4. The other diffraction peak is at 12.42° corresponding to the crystal plane (100). The dspacing here is 7.13 Å, which is analogous to in-plane structural packing and is in agreement with the tris-s-triazine unit (0.71 nm), confirming the constitution of the heptazine ring rather than the triazine ring in the carbon nitride moiety. There is a minor right shift of 0.03° and 0.01° for the (002) and (100) plane, respectively, revealing lattice strain on account of stronger bonding energy, higher condensation, and improved interlayer stacking order in the g-C3N4 obtained by the electro-synthesis. Peak broadening due to higher potential confirms the presence of quantum dots due to the transformation of the bulk material to its nanoscale regime. It is supported by the XRD of nanomaterials. In Figure , the g-C3N4 QDs show peaks at 3347 and 3412 cm -1 corresponding to stretching vibrations due to N-H confirming the presence of nitrogen and peaks at 3209 and 3080 cm - 1 due to O-H stretching in the system. A faint C-H stretching is observed at 2961 and 2875 cm -1 due to the presence of terminal alkanes. After electrochemical exfoliation, the new peaks are due to the formation of various functional groups. Melamine, after conversion, unfolds the C-H bending group at 1446 and 743 cm -1 due to terminal hydrogens present in QDs, respectively. The new 1648 and 1650 cm -1 bands a conjugated alkene C=C stretching. Similarly, a peak at 818 cm -1 reveals C=C bending frequencies due to the graphitic moiety. A new peak was observed at 1550 cm -1 due to N-O representing oxygen functionalities. A broad peak is noticed at 1077 cm -1 due to the OC-O-CO functional group in the system. These peaks are absent in melamine, which confirms the product being formed.
