A selective and sensitive fluorescent technique is proposed to determine o-phenylenediamine (OPD) and hydrogen peroxide (H2O2). This is carried out by utilizing enzyme mimics carbon dots (N/Cl-CDs) and fluorescent probe carbon dots (N/Zn-CDs). The synthesized N/Cl-CDs and N/Zn-CDs were characterized by transmission electron microscopy (TEM), X-ray powder diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS), and Ultraviolet-visible spectrophotometry techniques.
