Metal-organic frameworks (MOFs) are considered ideal candidates for H2 physisorption materials due to their high surface area and tunable pore structures/environments. However, interaction with hydrogen is too weak fully exploit advantages, necessitating the exploration of effective adsorption enhancement strategies. Here, a defective MOF-801 reported as an material investigate by charge-inducing. Based on excellent stability MOF-801, retains good porosity after acid vapor etching, compared initial (810 m2 g-1), reaching up 970 g-1. The mild etching method leads excess charges around zirconium (Zr) forming specific sites heat, inducing polarization, enhancing capacity. total uptake increases from 5.02 wt.% (MOF-801) 8.58 (Cl@MOF-801) at 77 K 80 bar. Additionally, exhibits cycling performance, stably 10 times 8 MPa maintaining capacity 8.56 wt%. results reveal that tuning heat charge induction promising strategy potential porous efficient storage.
