Abstract:
In this experimental work, we propose for the first time a simple, effectual and green approach to produce pure Dy2Ce2O7 nanostructures employing a novel fuel, Phoenix dactylifera extract. The role of the utilized amount of Phoenix dactylifera extract on the morphological characteristics, electrochemical hydrogen storage and also Coulombic efficiency of Dy2Ce2O7 was examined, for the first time. The characteristics and performance of Dy2Ce2O7 was found to be influenced through alteration in the utilized amount of Phoenix dactylifera extract. Multiple investigations have been done to analyze and confirm the formation as well as characterization of Dy2Ce2O7 nanostructures. Further, we investigated the performance of different Dy2Ce2O7 structures (produced employing with varied dosages of Phoenix dactylifera extract) in electrochemical hydrogen storage through chronopotentiometry route in basic medium. The findings point out that very uniform Dy2Ce2O7 nanoparticles formed employing 3 ml of Phoenix dactylifera extract can display superior performance to store hydrogen. This sample illustrates the great discharge capacity (2715 mAh/g) also high Coulombic efficiency (63.24%). Also, application of novel and green fuel (Phoenix dactylifera extract) can lead to preparation of Dy2Ce2O7, which can be efficiently utilized to store hydrogen (clean energy carrier) as a potential material, and resulting into decrement in the environmental pollution.
