Unveiling the synthesis of CuCe2(MoO4)4 nanostructures and its physico-chemical properties on electrochemical hydrogen storage

Abstract

The secondary energy sources, like hydrogen, is a key enabling energy carrier for the advancement of fuel cell technology. Hydrogen has a low volumetric energy density; therefore, its transportation is costly, and requires a large area. Solid-state hydrogen storage is a key solution for the promoting hydrogen in stationary power, portable power, and transportation applications. To keep these challenges up, this paper integrates production design of a novel solid-state-nanosized-mixed metal oxides (MMOs), CuCe2(MoO4)4 nanostructures via Pechini method, structural and morphological assessments, and its respective hydrogen storage properties. The electrochemical properties of the samples with morphological diversity have unveiled an exceeded discharge capacity (∼1320 mA h/g) of the sample which designed in neutral medium (pH = 7), having a specific surface area of 7.90 m2 g−1 and mean pore size of 37.07 nm.
