Abstract

The invention belongs to the technical field of storage and transportation of a new energy source namely hydrogen energy, and in particular relates to an ammonia borane composite hydrogen storage material and a preparation method thereof. The ammonia borane composite hydrogen storage material is prepared by loading ammonia borane into a porous coordination polymer by adopting an impregnation method. The composite material disclosed by the invention reduces the thermal decomposition hydrogen release temperature of ammonia borane, accelerates hydrogen release kinetics, avoids generation of volatile byproducts, solves technical obstacles for taking ammonia borane as a hydrogen source material, and provides probability of applying a hydrogen energy source to vehicles and industries. Meanwhile, the preparation method is simple and feasible, low in cost and good in effect.

Description

technical field [0001] The invention belongs to the technical field of storage and transportation of new energy hydrogen energy, and in particular relates to a borane ammonia composite hydrogen storage material and a preparation method thereof. Background technique [0002] Energy is an important material basis and driving force for the development and progress of human society. With the continuous depletion of global traditional energy sources, the development of efficient and environmentally friendly new energy sources is imminent. Hydrogen is considered to be a good alternative energy source due to its advantages of simple preparation and non-polluting combustion products. However, there are still some technical bottlenecks in the application of hydrogen in industry and transportation, that is, how to transport safely, efficiently and economically. [0003] Traditional hydrogen storage methods include high-pressure hydrogen storage and liquefied hydrogen storage. High-p...
