摘要： 光催化固氮技术以清洁的太阳能作为驱动能源，使用丰富的氮气和水作为原料，秉持绿色可持续的发展原则，是一项富有潜力的氨合成技术。然而，光催化氮气还原反应效率普遍较低，严重制约了该技术的应用与发展。本研究在介绍氮气还原过程的基础上，指出目前光催化固氮体系面临的主要挑战，围绕增强光吸收、加速光生电荷的分离与转移和促进N2吸附活化方面，结合近几年文献报道的光催化固氮典型案例重点综述了半导体材料的改性策略，最后对该领域的未来发展趋势进行了分析与展望。

Abstract: Photocatalytic nitrogen fixation technology takes clean solar energy as the driving energy, using rich nitrogen and water as raw materials. Adhering to the principle of green and sustainable development, it is a potential technology for ammonia synthesis. However, the reaction efficiency of photocatalytic nitrogen reduction is generally low, which seriously restricts the application and development of this technology. Based on the introduction of nitrogen reduction process, the main challenges of photocatalytic nitrogen fixation system are pointed out in this paper at present. The modification strategies of semiconductor nanomaterials and the cases for photocatalytic nitrogen fixation reported in recent years are reviewed mainly from enhancing light absorption, accelerating the separation and transfer of photogenerated charges, and promoting N2 adsorption and activation. Finally, the future development trend of this field is analyzed and prospected.
