Abstract

In this study, we investigated the use of electrocatalysts, PMAc, PMAc-g-CNT, Ni/PMAc, and Ni/PMAc-g-CNT for water splitting and supercapacitor applications. Our results showed that the Ni/PMAc-g-CNT catalyst exhibited superior properties in terms of electrochemical activity, stability, and energy storage capacity. The Tafel slope for OER was found to be 471.25 mV dec(-1), which was lower than other catalysts studied. The capacitance value of the Ni/PMAc-g-CNT catalyst was 35.23 F/g at 0.5 A/g current density, which was higher than the Ni/PMAc catalyst. These findings provide a novel and detailed insight into the performance of these catalysts and suggest that the Ni/PMAc-g-CNT catalyst is a promising material for both water splitting and supercapacitor applications.
