氢能作为洁净、理想的二次能源,已受到世界各国的广泛关注。然而,氢的储存技术仍然是制约氢能商业化应用的关键技术。利用储氢材料进行储氢被认为是一种安全、高效的固态储氢方式。因此,开发新型高容量的储氢材料与储氢技术成为氢能领域研究的热点之一。纳米限域是将材料填充到纳米孔道里,利用材料和纳米孔道的相互作用促进反应的进行,为化学反应提供一个独特的微环境。近年来,纳米限域逐渐发展成为改善储氢材料热力学和动力学的新方法。本文综述了纳米限域的储氢材料的研究进展,从纳米限域的储氢材料制备、储氢性能、反应机理和存在的问题等方面进行讨论,并指出了纳米限域储氢材料的发展趋势。
As a clean and ideal energy source, hydrogen energy has received extensive attention in recent years. However, the technology for hydrogen storage is still the key technology restricting the application of hydrogen commercialization. Hydrogen storage materials are considered to be safe, efficient way for solid-state hydrogen storage. Therefore, the development of new high-capacity hydrogen storage materials and hydrogen storage technology is one of the hot topics nowadays. Nanoconfinement is to fill the materials in the nanopores. By using the interaction between the filled materials and nanopore, the reaction is promoted. In recent years, nanoconfinement has become an effective way to enhance the kinetics and thermodynamics of the hydrogen storage
