Hydrogen storage gets real | Feature | Chemistry World
Long’s lab has been making their MOFs ‘stickier’ by adding low-coordinate metal ion sites into the MOF. His team has created MOFs in the right binding energy ballpark – but hit another problem. 1 ‘Using metal ions is relatively heavy,’ Long says, which means these materials don’t hold enough hydrogen relative to their weight.
