摘　　要：近年来,笼型水合物储氢已成为储氢研究的热点之一。采用激光拉曼光谱开展了以氮气水合物为载体的储氢实验研究。在较为温和的条件下(15MPa,-18℃),使合成的氮气水合物与氢气发生反应,对反应产物的拉曼光谱分析结果显示,氢气分子进入到水合物的笼型结构中,并且呈现出多分子的笼占有状态;氮气水合物与氢气的反应时间是影响储氢效果的重要因素。研究结果表明,氮气水合物有希望成为一种有效的储氢介质。Recently, hydrogen storage using clathrate hydrate as a medium has become a hotspot of hydrogen storage research. In the present paper, the laser Raman spectroscopy was used to study the hydrogen storage in nitrogen hydrate. The synthetic nitrogen hydrate was reacted with hydrogen gas under relatively mild conditions （e. g. 15 MPa, -18℃）. The Raman spectra of the reaction products show that the hydrogen molecules have enclathrated the cavities of the nitrogen hydrate, with multiple hydrogen cage oceupaneies in the clathrate cavities. The reaction time is an important factor affecting the hydrogen storage in ni- trogen hydrate. The experimental results suggest that nitrogen hydrates are expected to be an effective media for hydrogen storage.
