Clean synthesis of biocarbon-supported Ni@Pd core–shell particles via hydrothermal method for direct ethanol fuel cell anode application

Direct ethanol fuel cells (DEFCs) are devices for clean and sustainable energy production, where the generation of electrical energy occurs as a result of the anodic ethanol oxidation reaction (EOR). One of the main challenges of these devices is the development of cost-efective and sustainable anod...
