Abstract

The invention discloses a carbon nanosphere loaded ammonia borane hydrogen storage material prepared from carbon nanosphere supported ammonia boran, and carbon nanospheres are solid carbon nanospheres 100-200nm in diameter. The preparation method includes the steps: ultrasonically dispersing the carbon nanospheres in a tetrahydrofuran solvent; dissolving ammonia borane in the tetrahydrofuran solvent; mixing and stirring well the two solutions, and subjecting the uniform mixed solution to vacuum drying to remove the solvent to obtain a target product. The carbon nanosphere supported ammonia borane hydrogen storage material has the advantages that by adoption of the ammonia borane and the carbon nanospheres as raw materials for preparation of the carbon nanosphere supported ammonia borane hydrogen storage material at a low temperature, pyrolytic hydrogen desorption temperature of the ammonia borane can be effectively lowered, and generation of harmful substances such as borazole, diborane and ammonia is effectively inhibited; low heat release in a hydrogen desorption process is realized, and regeneration of reaction products through a solid-gas reaction or a chemical process under relatively mild conditions is facilitated.

Description

technical field [0001] The invention relates to a hydrogen storage material and technology for new energy hydrogen energy, in particular to a carbon nanosphere-loaded ammonia borane hydrogen storage material and a preparation method thereof. Background technique [0002] With the continuous development of the world economy, people's demand for energy is increasing rapidly, and fossil energy with limited resources will not be able to meet the needs of rapid economic development. People are trying to find alternative energy sources for fossil energy, including renewable energy and other new energy sources. It has become the common wish of people to develop a new type of fuel that is renewable, has high combustion value, is easy to use and does not pollute the environment. Hydrogen energy is an efficient and clean energy with high combustion value and no pollution. In the future energy system, hydrogen energy can become a terminal energy that is equally important and complemen...
