Lithium-doped covalent organic frameworks show potential for hydrogen storage. These materials can achieve nearly 7% gravimetric adsorption capacity for hydrogen gas at room temperature and high pressure.
Area of Science:
- Materials Science
- Chemical Engineering
- Theoretical Chemistry
Background:
- Hydrogen storage is critical for clean energy technologies.
- Covalent organic frameworks (COFs) are porous materials with tunable properties.
- Developing efficient hydrogen adsorbents is an ongoing challenge.
Purpose of the Study:
- To investigate the hydrogen storage potential of lithium-doped covalent organic frameworks.
- To predict the gravimetric adsorption capacities of these novel materials using theoretical methods.
Main Methods:
- A multiscale theoretical method was employed.

The mechanism proceeds in three steps. First, the nucleophilic hydride ion attacks the carbonyl carbon of the acid halide to form a tetrahedral intermediate. Next, the carbonyl group is re-formed, and the halide ion departs as a leaving group, generating an aldehyde. A second nucleophilic attack by the hydride yields an alkoxide ion, which, upon protonation, gives a primary alcohol as...
