Pt alloy nanoparticles present the most probable candidate to be used as the cathode cathodic oxygen reduction reaction electrocatalyst for achieving commercialization targets of the low-temperature fuel cells.It is therefore very important to vegas golden knights background understand its activation and degradation processes.Besides the ones known from the pure Pt electrocatalysts, the dealloying phenomena possess a great threat since the leached less-noble metal can interact with the polymer membrane or even poison the electrocatalyst.In this study, we present a solution, supported by in-depth advance electrochemical characterization, on how to suppress the removal of Cu sex shop arles from the Pt alloy nanoparticles.
