金属-氮-氢体系是目前最具发展前景的储氢材料体系之一，但是其吸放氢性能还需要进一步改善以满足实用化的需求。而微波辐射技术以其特殊的热效应和非热效应，可极大促进化学反应的进行，在化工、石油、冶金材料等领域已有大量的成功应用。将微波技术应用于金属氮氢储氢材料性能改善的工作尚未见报道。本项目拟研究微波辐射对于金属-氮-氢体系的吸放氢行为的影响规律。通过研究微波辐射与反应物中各种可极化因子的耦合作用，包括NH3极性分子、N-H极性键、晶格缺陷等，改善金属-氮-氢体系的微波加热性能；通过微波辐射和添加剂的协同作用来改善金属-氮-氢体系的吸放氢性能；通过对比普通加热和微波加热来系统研究微波的热效应和非热效应对金属-氮-氢体系吸放氢性能改善的作用机理。本项目有望开辟金属-氮-氢体系吸放氢性能的微波改性途径，为微波辐射技术在储氢材料领域的应用提供一定的理论和实践基础。

Metal-N-H system is one of the most promising hydrogen storage systems. However, a further improvement to the hydriding/dehydriding properties is necessary for the system to meet the demand of practical application. Meanwhile, the technique of microwave radiation has already been successfully utilized in chemistry, petroleum and metallurgy industry, attributed to its special thermal and non-thermal effects which could significantly promote the chemical reaction. Study of the microwave on the improvement of metal-N-H system has not yet been reported. This work is planning to investigate the effects of microwave on the hydriding and dehydriding properties of Metal-N-H systems. In this project, we will study the interactions between microwave radiation and the polarizable factors of reactants such as NH3 molecular, N-H bond, and lattice defects, in order to improve the microwave heating properties of the Metal-N-H systems. The combined effects of microwave and microwave absorbents will be studied in order to improve the hydriding and dehydriding properties of metal-N-H systems. The effects of microwave heating and traditional heating will be compared in order to study the thermal and non-thermal effects of microwave on the hydriding/dehydriding properties of metal-N-H systems. Through this work, an innovative method to improve the hydriding and dehydridng properties of metal-N-H hydrogen storage systems could be established. This research could provide theoretical and technical basis to the utilization of microwave technique in hydrogen storage materials.
