A few days ago, the research team of Professor Luo Min from Ningxia University firstly controlled the nanocomposite electrocatalyst material through a two-step method (carbonization and oxidation heat treatment process) to develop a highly efficient room temperature nitrogen-fixing electrocatalyst with a novel core-shell structure. Related papers were published online in the American Chemical Society-Applied Materials and Interfaces. Under the global background in which the energy crisis and environmental problems are becoming increasingly prominent, green, environmentally friendly and low energy consumption ammonia synthesis methods are of great significance. In recent years, electrochemical nitrogen fixation (NRR) has gradually become a widely studied new route for ammonia synthesis. The researchers prepared nano-composite electrocatalyst materials based on metal-organic framework through carbonization and oxidation heat treatment process technology, and then developed a highly efficient electrocatalyst with a novel core-shell structure Co3O4 @ NC for electrochemical nitrogen fixation at room temperature. The study found that the new composite catalyst has an ammonia yield and Faraday efficiency of up to 42.58 μg / h / mg and 8.49% in 0.05 mol / L sulfuric acid electrolyte, which is superior to most reported NRR electrocatalysts. In addition, because nitrogen is confined in the "shell", it is more conducive to high-frequency collisions and increases the concentration of NRR intermediate products, which can further improve the electrocatalytic performance. This research not only developed new and efficient electrocatalysts, but also provided new ideas for exploring more cheap and green non-precious metal catalysts in the field of electrocatalytic nitrogen fixation.
