In the present study, a novel heterogeneous catalyst was successfully fabricated through the decoration of palladium nanoparticles on the surface of designed Fe<sub>3</sub>O<sub>4</sub>-coffee waste composite (Pd-Fe<sub>3</sub>O<sub>4</sub>-CWH) for the catalytic reduction of nitroarenes. Various characterization techniques such as XRD, FE-SEM and EDS were used to establish its nano-sized chemical structure. It was determined that Pd-Fe<sub>3</sub>O<sub>4</sub>-CWH is a useful nanocatalyst, which can efficiently reduce various nitroarenes, including 4-nitrobenzoic acid (4-NBA), 4-nitroaniline (4-NA), 4-nitro-o-phenylenediamine (4-NPD), 2-nitroaniline (2-NA) and 3-nitroanisole (3-NAS), using NaBH<sub>4</sub> in aqueous media and ambient conditions. Catalytic reactions were monitored with the help of high-performance liquid chromatography.
