The recent past has witnessed an exponential increase in the demand for energy conversion, storage, and consumption technologies. The development of inexpensive, efficient, durable electrode materials and catalysts is critical to the success of these technologies/devices. Here, we present a simple, sustainable, cost-effective, and scalable method for preparing stable and effective nickel/nickel oxide nanoparticles on highly porous Ndoped graphitic carbon. The catalysts were prepared by a direct pyrolysis method at different temperatures under an argon atmosphere. When compared to other catalysts, the carbon material synthesized at 800 °C
