Activated Cu/Cu2O foam with Ni nanoparticles for electrocatalytic activity enhancement of hydrogen evolution reaction (HER) in acidic media

Publication date: Available online 5 November 2018Source: Journal of Industrial and Engineering ChemistryAuthor(s): Nastaran Farahbakhsh, Sohrab SanjabiAbstractThis paper presents the hydrogen evolution reaction of Cu/Cu2O foam by Ni nanoparticles, deposited by electrodeposition and electroless plating. The structure and morphology of Cu/Cu2O foam and deposited Ni nanoparticles were studied by FE-SEM and XRD. The foam with Ni nanoparticles had a high specific surface area measured by BET. The synthesized Cu/Cu2O foam/Ni electrode presented high electrocatalytic activity for HER, with low overpotential of −290 mV vs. Ag/AgCl and Tafel slope of 50 mV decade−1. The stability study of the developed electrodes showed a high stability in short-term.Graphical abstract
