The present work demonstrates an eco‐friendly and facile method for the synthesis of tapioca and potato starches incorporated by silver nanoparticles hereafter named (T‐Ag/NPs) and (P‐Ag/NPs), respectively. The analysis of UV–vis showed the appearance of surface plasmon resonance. The TEM analysis shows the formation of highly distributed Ag/NPs with an average diameter and standard deviation of 19.65 ± 2.45 and 12.27 ±7.39 nm for (P‐Ag/NPs) and (T‐Ag/NPs), respectively. The prepared (T‐Ag/NPs) show remarkable potential applicability in energy as low‐cost electrode material compared with (P‐Ag/NPs). They are used as a non‐precious catalyst for oxygen reduction reaction (ORR) in the alkaline medium. The presence of starch promotes long‐term stability up to 1000 cycles and avoid the dissolution and agglomeration of silver nanoparticles. The (T‐Ag/NPs) show significant stability and reproducibility.
