| As a new type of green energy, its development and utilization has attracted great attention around the world. However, hydrogen can only be used if its storage and transportation problems are solved, with the recent technology innovation, researchers found that hydrogen storage materials can effectively solve this problem. Today, a variety of hydrogen storage materials continue to emerging, but each hydrogen storage system has its downsides and can not be ignored. So far, the techniques of hydrogen energy are still not perfect in the research and development. As a result, none of the systems are able to meet the conditions of applications in life and large-scale industries. Therefore, the development of efficiency of hydrogen storage technologies determines whether hydrogen can be large-scale developed and utilized or not.This experiment mainly focuses on a new hydrogen storage system—HPSB hydrogen storage system. The system was found by the present research group, and the catalytic performance of Sodium borohydride’s hydrogen release and the absorption/desorption of the HPSB hydrogen storage systems are studied, also the influence of doping TiO2 on HPSB hydrogen storage systems absorption/desorption properties is studied, and concludes the ratio of best catalyst activity and absorption/desorption performance.The results show: the catalyst activity of different porpotion has great difference, which can be conclued that when the catalyst weighs 5% in whole reactants, and the content of CoB is 60%, Sodium borohydride reaches its maximum hydrogen release amount, that is 2520 m L/g NaBH4; Test in the pct system of absorption/desorption properties of HPSB(Y2O3) and HPSB(Y2O3)-TiO2 hydrogen storage system, the result shows the properties of HPSB(Y2O3)-TiO2 hydrogen storage system is better than HPSB(Y2O3) hydrogen storage system, and the best absorption/desorption properties shows at CoB:Y2O3=2:3, the maximum hydrogen release amount is 2.14 wt%. |
