Pt/Fe/NiO on CNT/CP substrate as a possible electrode of nano chip devices
In the present work, PtFeNiO/CNT/CP electrode was prepared with ethylene glycol reduction process. Growth of interconnected CNTs on the CP surface, surface morphology and degree of hydrophobicity were studied with Field emission scanning electron microscopy, Energy dispersive spectroscopy, Transmission electron microscopy, Thermal gravimetric analysis and Contact angle techniques. Polarization, P–I (power density–current density) curves and Electrochemical impedance spectroscopy analysis (determined by Half cell testing) were applied to investigation of electrochemical properties of the prepared electrodes. The results indicated that the improvement of performance and reduction of charge transfer resistance PtFeNiO/CNT/CP compared to PtFeNiO/CP, CNT/CP, CP and commercial catalyst Pt/C (10 wt%) loaded on CP, can be attributed to strong adhesion of in-situ CNTs to the CP, lower agglomeration of CNTs, outstanding electrical and thermal conductivity of CNT along with high catalytic activity of triple catalyst. These results make them promising candidates for the future of nano chip devices.
