In this paper, we report our study on the effect of lower potential (El) of square-wave deposition of bimetallic on its electrochemical properties and photocatalytic activity of methylene blue (MB) dye degradation. The electrochemical properties were examined using cyclic voltammetry (CV) and Electrochemical Impedance Spectroscopy (EIS) technique. The MB photodegradation measured under ultraviolet (UV) radiation indicated a high photocatalytic activity was obtained from the bimetallic AgPt with low impedance value but high specific capacitance value. The bimetallic AgPt synthesized at a lower potential of -0.5 V vs Ag/AgCl showed a highest photodegradation performance of MB dye. This work showed the effects of El that applied square-wave deposition technique on modifying bimetallic AgPt properties that enhanced its catalytic properties. © 2022 Author(s).
