络合氢化物具有较高的重量储氢密度,已成为国内外研究的热点。孔性介质由于高比表面积、孔径均匀可调以及良好热稳定性而备受关注。研究表明,实现孔性介质负载的络合氢化物可有效地改善其储氢性能。本文简述了孔性介质的结构特征和物化特性,着重阐述了孔性介质负载催化络合氢化物的制备方法、脱/加氢性能的影响及其催化机理的研究进展,并指出了需要研究的科学问题。
Complex hydride has a high density of hydrogen storage density, has become a hot spot at home and abroad. Porous media are attracting much attention due to their high specific surface area, uniform pore size and good thermal stability. Studies have shown that the complex hydride to achieve the loading of porous media can effectively improve its hydrogen storage performance. In this paper, the structural characteristics and physico-chemical properties of porous media are briefly reviewed. The preparation methods of hydrazine-supported hydride, the influence of dehydrogenation / hydrogenation performance and its catalytic mechanism are emphatically described. It is pointed out that it is necessary to study Scientific issues.
