Abstract

The invention discloses a preparation method of a nano hydrogen storage material. The preparation method comprises the following steps of 1S, carrying out ultrasonic cleaning on porous copper; 2S, preparing a copper oxide nanowire through high-temperature oxidation in an oxygen atmosphere; 3S, preparing a titanium oxide coated copper oxide nanowire by a sol-gel method; and 4S, performing magnesiumdeposition on the nanowire by using a magnetic filtering technology. The method is based on the high-temperature oxidation, ion implantation, the sol-gel method and the magnetic filtration depositionmethod, and can be used for conveniently absorbing and desorbing hydrogen to form an ultra-nano composite structure; hydrogen absorption material prepared by the method has the characteristics of strong hydrogen absorption capacity, low hydrogen desorption temperature, self-cleaning and the like; and the hydrogen absorption material disclosed by the invention has an important application prospectin the aspect of hydrogen energy.

Description

technical field [0001] The invention belongs to the field of new energy, and in particular relates to a preparation method of a hydrogen storage material. Background technique [0002] With the development of industry and the improvement of people's material living standards, the demand for energy is also increasing day by day. Since the energy used in recent decades mainly comes from fossil fuels (such as coal, oil and natural gas, etc.), and its use inevitably pollutes the environment, and its reserves are limited, so it is urgent to find renewable green energy. As a green energy and energy carrier with abundant reserves, wide sources and high energy density, hydrogen energy is attracting widespread attention. The utilization of hydrogen energy needs to solve the following three problems: hydrogen production, storage, transportation and application, and the storage and transportation of hydrogen energy is the key to the application of hydrogen energy. Hydrogen exists in ...
