  1. 1 day ago · The C dl value of Rh 1 Ru 1 O x-CNFs-350 is 87.9 mF cm −2, which is 1.79, 3.98, and 14.90-fold that of Pt/C, RhO x-CNFs-350 and RuO x-CNFs-350, respectively. Rh 1 Ru 1 O x -CNFs-350 has the highest ECSA value, demonstrating that more exposed active sites are present in Rh 1 Ru 1 O x -CNFs-350, which is beneficial for enhancing the electrocataltyic activity of HER.
