Synthesis of NiCo-LDH/Ti3C2Tx/NF and NiCo-LDH/NF

0.77 g of Ni(NO)₂·6H₂O, 0.38 g of Co(NO)₂·6H₂O, 1.5 g of cetyl trimethylammonium chloride (CTAC), 50 ml of deionized water and 10 ml of methanol were added into an autoclave and mixed evenly, then Ti₃C₂T_x/NF was placed into the autoclave and reacted for 18 h at 180 °C to grow NiCo-LDH on the surface of Ti₃C₂T_x/NF and obtained NiCo-LDH/Ti₃C₂T_x/NF. When the reaction was completed, the NiCo-LDH/Ti₃C₂T_x/NF hybrid electrocatalyst was rinsed with deionized water and dried under vacuum at 60 °C for 5 h.

NiCo-LDH/NF was prepared by directly growing NiCo-LDH on a clean NF substrate under the same conditions.
