Introduction: Chlorophenols (CPs) have become prevalent in the manufacture of herbicides, fungicides, pesticides, insecticides, pharmaceuticals, and dyes, contributing significantly to water pollution. Addressing this challenge, various treatment methods such as incineration, electrochemistry, photochemistry, biotechnology, catalytic hydrodechlorination been explored reduce toxic chlorophenol contaminants. Hydrodechlorination stands out an efficient technique for removal chlorine atoms. The dispersion metal nanoparticles on supported materials enhances activity by increasing specific surface area. Among these, carbon-supported nickel-cobalt-iron emerge promising catalysts 2-chlorophenol. Method: This study employs a chemical reduction method at high temperatures under inert gas atmosphere synthesize ternary nanocatalysts, aiming detoxify soil from pesticide residues. physicochemical properties these nanocatalysts were characterized using energy-dispersive X-ray spectroscopy (EDX), diffraction (XRD), scanning electron microscopy (SEM), transmission (TEM). Their was assessed through chromatography with flame ionization detector (FID). Results: analysis revealed that metallic are uniformly dispersed carbon support, particle sizes ranging 10 60 nm average size 30 nm. (HDC) 2-chlorophenol (2-CP) achieved satisfactory conversions reaction conditions. Conclusion: demonstrated effective 2-chlorophenol, highlighting their potential application chloroorganic contaminations future.
