Investigation of ordered Pd based intermetallic nanoparticles as efficient and stable catalysts in fuel cell application

Abstract

Search of sustainable solutions to the looming energy crisis has become one of the major challenges on the way to get rid of our dependence on fossil fuels.1,2 Over the last few years several technologies have been implemented to provide electrical energy from different renewable sources such as solar energy, wind power generators.3 But the mismatch between supply and demand leads researchers to find out integrated solutions with advanced energy conversion and storage.1,2,4-6 In recent years noble metal nanocrystals have been considered as the benchmark materials due to their superior catalytic performances in the field of ?electrochemical energy conversion and storage.7 Noble metal based materials have been widely used in various electrochemical reactions like hydrogen or small molecule oxidation, oxygen reduction in fuel cells
