Abstract
Exploring the electrocatalyst prepared by novel methodology is highly demanding for overall water splitting reaction. Herein, we have developed a Palladium and Cobalt based (PdCo) nanocomposite that serves as a dual active electrocatalyst for both hydrogen evolution reaction (HER) (0.5 M H2SO4, 1 M KOH) and oxygen evolution reaction (OER) (1 M KOH). The present nanocomposite is synthesised via reduction of reverse mixed metallomicellar core formed using palladium and cobalt metallosurfactants. The main approach of this methodology is to control the size of nanoparticle within the core of the metallomicelle with smaller and limited range of particle size distribution. This approach is cost effective and has reduced reaction time. The present electrocatalyst require 78 mV, and 310 mV of overpotential to achieve 10 mA cm−2 of current density for HER (acidic) and OER (basic), respectively. This study provides a new methodology for the development of a new generation electrocatalyst.
