RECENT ADVANCES IN HYDROGEN EVOLUTION REACTION USING FIRST-ROW TRANSITION METAL COMPLEXES AS CATALYST

Abstract

The precise use of an electrocatalyst for the HER reaction mainly depends on synthesis cost, durability, and over potential. Recently there is promising research for electrocatalyst synthesis using first-row transition metals. Working towards this herein we present synthesis, physio-chemical characterization, and hydrogen evolution activity of amino guanidium metal naphthoate complexes. The obtained electrocatalysts were characterized by element analysis, IR spectra, UV-Visible spectroscopy, TG-DTA, and powder-XRD. The thermal behavior of these compounds has been studied by simultaneous TG-DTA techniques. The isomorphic nature of the metal complexes is evident from powder-XRD data.
