“…13 In their study, nickel nanoparticles were reported to enhance electronic conductivity and electrocatalytic ability for the counter electrode. Ni nano-templates have also been used in various other electrochemical devices, e.g., sensors, [14][15][16][17] capacitors, [18][19][20][21] catalysts, 22 and energy storage devices, 23 intending to improve their performance.…”
