Study on the Hydrogen Precipitation Performance of Nanofiber Aerogel-based Platinum-carbon Catalysts

Abstract

Abstract Clean energy development is particularly important in the context of increasing environmental pollution caused by fossil energy consumption. In this paper, a carbon aerogel-loaded platinum (Pt/CNF As) catalyst prepared by freeze-drying and combined with sodium borohydride reduction can be used in a hydrogen evolution reaction (HER) to produce the most promising clean energy source and hydrogen energy. The plastic deformation is only 16% after 1000 compression cycles at 50% strain. In addition, compared with commercial Pt/C catalysts, Pt/CNF As eliminates the complicated process of working electrode preparation without reducing electrocatalytic activity and has an overpotential of only 40 mV (10 m A/cm2) and an active area of 124 mF/cm2.
