摘　　要：空气中含有78%的氮气,是较为理想的氮来源。迄今为止,工业上NH3的合成主要采用HaberBosch法,即氮气和氢气在高温高压条件下合成氨,其具有高能耗、高污染等缺点。因此,亟需开发绿色经济的合成氨方法。近年来,光催化固氮已成为研究的热点之一。它具有独特的优势,如反应体系简单、反应条件温和、环境友好等。介绍了光催化固氮的催化原理并对文献中报道的固氮金属催化剂进行分类整理,着重介绍了含钛、铁类金属催化剂的优势及最新的研究进展。Air contains 78% nitrogen,which is a more ideal source of nitrogen.So far,the industrial synthesis of NH3 has mainly used the Haber-Bosch method,nitrogen and hydrogen are used to synthesize ammonia under high temperature and high pressure,which has the disadvantages of high energy consumption and high pollution.Therefore,there is an urgent need to develop green and economical methods for ammonia synthesis.In recent years,photocatalytic nitrogen fixation has become one of the hotspots for research.It has unique advantages,such as simple reaction system,mild reaction conditions,and environmentally friendly.In this paper,the catalytic principle of photocatalytic nitrogen fixation was introduced,and the metal catalysts for nitrogen fixation reported in the literature were classified,the advantages of titanium-containing and iron-containing metal catalysts and the latest research progress were discussed.
