520			_aThe synthesis of carbon-based nanoparticles (C-BNPs) from organic waste has recently garnered considerable attention in the field of nanomaterials, attributed to their versatile electrical and chemical properties with a wide range of applications. Calamansi peel waste as a precursor was utilized to produce C-BNPs, which were subsequently calcined and refluxed with nitrogen dopant from urea. The synthesized nitrogen-doped carbon-based nanoparticles (NC-BNPs) underwent different analytical characterizations to evaluate their properties and characteristics. The results obtained from UV-vis show that NC-BNPs have enhanced optical properties compared to C-BNPs. It was supported by the results obtained from the spectrofluorophotometer, wherein NC-BNPs illustrate a broader peak and increased intensity. As for the confirmation of successful doping of nitrogen into the C-BNPs matrix, it was verified using FTIR, wherein a rabbit-like peak found at between 3394 and 3253 cm- 1 for a primary amide indicated that there was a presence of nitrogen. Moreover, the morphology and particle size distribution of the NC-BNPs were analyzed using TEM and ImageJ version 1 software. It was concluded that the synthesized NC-BNPs have heterogeneous features. The nanoparticles were of spherical, rod-like, and elongated form with aggregation and had an approximate mean size of 16.355 nm with a standard deviation of 4.804, which indicated that there was a wider range size distribution of an integration of small and large particles compared to the average size. In terms of photocatalytic degradation, it showed potential application with a degradation rate of 44.44%; however, further optimization is advised to achieve optimum efficiency.
