Cubic Copper Hexacyanoferrates Nanoparticles: Facile Template-Free Deposition and Electrocatalytic Sensing Towards Hydrazine
Figure 1
(a) Cyclic voltammograms (30 cycles) of CuHCF films at the glassy carbon electrode recorded in 0.25 M KH2PO3 + 0.125 mM CuSO4 + 0.125 mM K3[Fe(CN)6] solutions with Ag/AgCl reference electrode. Scan rate: 50 mV/s. Curves from inner to outer correspond to the 1th, 5th, 15th, 20th, 25th, and 30th cycles, respectively. (b) XRD pattern of the CuHCF film. (c) SEM image of copper hexacyanoferrates nanoparticles (CuHCFNPs). (d) Comparative cyclic voltammograms of the CuHCF-modified GCE in (A) 0.1 M NH4 NO3, (B) 0.1 M LiNO3, (C) 0.1 M KNO3, and (D) 0.1 M NaNO3 solutions. Scan rate: 50 mV/s.
