(A) Cyclic voltammograms of (a) bare GCE (Black), Ag@Co-Al/PoPD/GCE (Red) in absence of 2,4-DNP, Co-Al/GCE (Blue), Co-Al/PoPD/GCE (Green) and Ag@Co-Al/PoPD/GCE (Pink) in the presence of 1 × 10−3 M 2,4-DNP (pH 5) at the scan rate of 50 mVs−1. (B) Effect of pH (pH 3–9) (C) effect of scan rates (20–300 mVs−1) of Ag@Co-Al/PoPD/GCE, (D) Chronocoulometric curve of Ag@Co-Al/PoPD/GCE (inset fig: t1/2 vs Q).
