    • A porous wall hollow glass microsphere is provided having a diameter range of between 1 to 200 microns, a density of between 1.0 to 2.0 gm/cc, a porous-wall structure having wall openings defining an average pore size of between 10 to 1000 angstroms, and which contains therein a hydrogen storage material. The porous-wall structure facilitates the introduction of a hydrogen storage material into the interior of the porous wall hollow glass microsphere. In this manner, the resulting hollow glass microsphere can provide a membrane for the selective transport of hydrogen through the porous walls of the microsphere, the small pore size preventing gaseous or liquid contaminants from entering the interior of the hollow glass microsphere. A hydrogen storage material (e.g. Palladium) is introduced into the porous glass micropheres by subjecting them to partial vacuum, surrounding them with a solution containing the hydrogen storage material, increasing the pressure to force the solution into the spheres, drying them and finally reducing the hydrogen storage material .
    • 提供了多孔壁中空玻璃微球,其直径范围为1至200微米,密度为1.0至2.0gm / cc,具有限定平均孔径为10至1000埃的壁孔的多孔壁结构, 并且其中含有储氢材料。 多孔壁结构有助于将储氢材料引入多孔壁中空玻璃微球的内部。 以这种方式,所得到的中空玻璃微球可以提供用于通过微球的多孔壁选择性输送氢的膜,防止气体或液体污染物进入中空玻璃微球的内部的小孔径。 将储氢材料(例如钯)通过使其部分真空被引入多孔玻璃微球体中,用含有储氢材料的溶液围绕它们,增加压力以迫使溶液进入球体,将其干燥并最终减少 储氢材料。
