Due to extensive industrial use, a significant quantity of effluent containing methylene blue dye is released into a water source. It may cause toxicity to humans and aquatic fauna. Therefore, detecting and removing MB dye from the effluent is essential. For this goal, we synthesized dual application zinc oxide nanoparticles using coffee fruit (Coffea arabica) peel biomass as a reducing agent. SEM scans revealed spherical nanoparticles. The EDX spectral data indicated the existence of zinc and oxygen elements. The X-ray diffraction pattern exhibited crystallinity of ZnO. Under optimized conditions, the electrochemical impedance spectroscopy (EIS), cyclic voltammetry, and Differential Pulse Voltammetry (DPV) study was studied for the detection of MB, an impressively low detection limit (LOD) of 0.01771 ?M was recorded, The photocatalytic efficacy of ZnO nanoparticles demonstrated a significant 92.43% degradation of methylene blue under UV light. So, Coffea arabica biomass may play a vital role in synthesizing eco-friendly ZnO nanomaterials for environmental remediation applications. 2026 Elsevier B.V.
