An easily recoverable PANI/PdC catalyst was synthesized and thoroughly characterized using XRD, FTIR, and SEM techniques. Its catalytic efficiency was tested in Suzuki coupling, Dehydration, and Buchwald coupling reactions under varied parameters such as time, temperature, and catalyst loading. The catalyst facilitated the high-yield synthesis of biphenyl, benzaldehyde, and N-alkylated products with minimal experimental optimization. PANI/PdC demonstrated a strong synergistic effect, outperforming PANI alone in all three reactions. Moreover, it exhibited excellent antioxidant activity (82% at 3 mg/mL), highlighting its potential as a multifunctional material for industrial and biomedical applications.
