AI Technical Summary
In the prior art, the framework structure of metal-organic framework (MOF) materials is destroyed during high-temperature calcination, resulting in a reduction in specific surface area, insufficient exposure of active sites, disordered defect distribution, and difficulty in constructing multiphase heterogeneous interfaces, which limits the improvement of hydrogen storage catalytic performance.
A CeTix-MOF-derived bimetallic catalyst was prepared by calcining the CeTix-MOF precursor at a relatively low temperature (350℃) to form a porous carbon-supported titanium oxide composite structure, retaining part of the framework structure, thus constructing a high specific surface area and excellent catalytic performance, suitable for dehydrogenation modification of lithium aluminum hydride (LiAlH4) system.
This achieves the dissociation and diffusion of hydrogen molecules, improves the stability and activity of the catalyst, reduces energy consumption, and avoids high-temperature sintering.
