Abstract

A significant amount of research is currently being undertaken to decrease the overall cost which governs the running of electrolyzer technologies. If the cost associated with electrolyzers was significantly reduced, it would pave a path to the efficient and economical generation of clean molecular hydrogen that could be used as a feedstock to create energy. As of now, only a handful of materials can challenge the performance of the current state-of-the-art cathodic catalyst, platnium, utilized in porous exchange-membrane electrolyzer devices. Herein, we show that 6.6 wt % of Pt on a homemade graphene film can achieve comparable hydrogen evolution activity to bulk platinum metal and surpass that of non-noble metal materials on carbon films previously reported.
