Popis: Highlights 4-nm-thick Pt nanosheets (Pt-NSs) are electrochemically grown on Ti substrates for hydrogen evolution reactions. Highly uniform Pt-NS surface coverage with an ultralow loading of 0.015 mgPt cm−2 is achieved. 99.5% catalyst savings and about 237-fold higher catalyst utilization are demonstrated.
