 The researchers studied the effect of adding nickel oxide nanoparticles to a lanthanum nickelate thin film. They found that the addition of these particles increased the amount of oxygen evolved during electrochemical reactions, leading to higher efficiency. The researchers believe that the nanoparticles act as a bridge between the lanthanum and nickel atoms, allowing them to interact more effectively.
