The hydrolysate of sodium borohydride is a new hydrogen storage material,it shows good reversible capacities for hydrogen storage,under 5 MPahydrogen pressurevacuumcondition,after 3 minutes,it absorbs 150 at room temperature. It has been shown that both changing the catalysts forNaBH4 hydrolysis and adding catalysts directly into HPSB are two very effectivemethods tofurther improve HPSB hydrogen storage capacity.The dehydrogenation of HPSB-Y2O3 andTiO2-doped HPSB-Y2O3 were found to reach 2.4wt%and 4.6wt%,respectively. Importantly,the reversible dehydrogenation ability of HPSB-Y2O3 does not decrease after successive cycles.In comparison,the reversible dehydrogenation of HPSB-CeO2 is higher andreaches 5.9 wt%at 150 after hydro-gen adsorption for 5 min at room temperature under3 MPa hydrogen pressure.%硼氢化钠的水解产物是一种新的储氢材料，其良好的可逆储氢能力在5MPa氢气压力真空条件下3分钟后在室温下吸收氢150。根据报道，它已被证明，这两种改变的催化剂NaBH4水解和添加催化剂直接插入接口是两个非常有效进一步提高接口的储氢容量。对hpsb-y2o3脱氢TiO2分别掺杂均达到重量2.4%和重量4.6%。重要的是对hpsb-y2o3可逆的脱氢能力不下降后成功———超循环。相比之下，对hpsb-ceo2可逆脱氢高达到重量5.9%，在室温下5分钟后3MPa氢气压力150氢吸附。
