Abstract

The invention provides a tubular TiO2 synthesis method. The tubular TiO2 synthesis method comprises the following steps of: (2) dissolving TiOSO4 in mixed alcohol, and then adding diethyl ether to the mixed alcohol; (2) transferring the solution to a high-pressure reactor, and carrying out heating constant-temperature reaction in a homogeneous reactor to generate white precipitates; (3) sequentially centrifuging, washing, drying in vacuum and calcining the generated precipitates at high temperature, thus obtaining a finished product; and (4) mixing the prepared powder and LiBH4 to prepare the TiO-LiBH4. The synthesized tubular TiO2 can be used as a catalyst for hydrogen generation of LiBH4 and a range-limited carrier. The tubular TiO2 synthesis method has the advantages that the production process is simple, reaction conditions are easy to control, a template agent and a surface active agent are not needed, and the prepared tubular TiO2 can be used for greatly improving the hydrogen generation performance of LiBH4.

Description

technical field

[0001] The present invention relates to LiBH 4 In the field of hydrogen storage, especially a kind of tubular TiO 2 Synthetic methods and their applications. Background technique

[0002] As a clean and ideal secondary energy source, hydrogen energy has attracted widespread attention from all over the world. However, hydrogen storage is still a key technology that restricts the commercial application of hydrogen energy. In recent years, with the continuous expansion of the field of hydrogen storage materials, lithium borohydride (LiBH 4 ) as a typical representative of high-storage coordination metal hydrides has gradually become an emerging research hotspot of hydrogen storage materials.

[0003] Nano confinement is to fill materials into nanopores, and use the interaction between materials and nanopores to promote the reaction and provide a unique microenvironment for chemical reactions. In recent years, nanoconfinement has gradually developed into a ne...
