Anchoring Ni single atoms on Co 3 O 4 nanocubes as efficient electrocatalysts for enhanced hydrogen evolution reaction (HER)

Key Points

• Enhanced hydrogen evolution reaction occurs due to nickel single atoms anchored on cobalt oxide nanocubes.
• Key findings show that nickel loading is finely tuned through various hydrothermal synthesis cycles.
• The approach involves hydrothermal synthesis followed by nickel adsorption and reduction at 180 °C.
• This study highlights the potential for using single-atom catalysts in energy applications and emphasizes the efficiency of this method.
