(a–c) OER polarization curves corresponding to Tafel plots and OER overpotential values of NCS aerogel and NCS/CN composite aerogels (1CN, 3CN, and 5CN) composite aerogels. (d–f) HER polarization curves corresponding to Tafel plots and HER overpotential values for NCS aerogel and NCS/CN composite aerogels (1CN, 3CN, and 5CN) composite aerogels. (g) OER potential stability of 3CN aerogel at a 100 mA·cm^-2 current density. (h, i) Comparison of OER and HER overpotentials with reported electrocatalysts, respectively.
