Generation of structural defects in MOFs to facilitate hydrogen spillover mechanism


The overall objective of this research is to determine the capacity of hydrogen storage
MOFs. The thesis aims at investigating hydrogen adsorption optimization in MOFs
by engineering defects in the MOF. The findings are used to model MOFs with efficient
hydrogen uptake for hydrogen storage applications.
