(A) Cyclic voltammograms of g-C3N4/GCE(a), g-C3N4-CNTs/GCE(b), Pd/g-C3N4-CNTs/GCE(c) in 5 × 10−3 M [Fe(CN)6]3−/4− + 0.1 M KCl; (B) Cyclic voltammograms of Pd/g-C3N4-CNTs/GCE(a), GCE(b), g-C3N4/GCE(c), g-C3N4-CNTs/GCE (d) and Pd-g-C3N4-CNTs/GCE (e) in the absence (a) and presence (b, c, d and e) in 0.1 M PBS (pH 10.5) solution containing 0.5 mM EE2 at a scan rate of 70 mV/s.
