SEM images show the electrodeposited CNHs on the CFME surface. (A-B) CNH/CFME prepared from electrodeposition of 0.5 mg/mL CNH using 10 cycles of CV scanned between –1.0 V to +1.0 V at a scan rate of 50 mV/s. (C-D) ox-CNH/CFME prepared from the oxidative etching of CNH/CFME in 1 M NaOH at a constant potential of +1.5 V vs. Ag/AgCl for 1.5 min.
