This study focused on development and safety evaluation of porous materials (such as metal-organic frameworks, MOFs) to improve the uptake of methane derived from the shale gas. The shale gas is one type of unconventional natural gases with lower permeability than 1 millidarcy. At the beginning of this century, shale gas has become one of the important sources of natural gas in the USA and the rest of the world. Various studies indicated that the shale gas will expand into a world energy supply. Therefore, production and storage of major components (CH<sub>4</sub>) are critical for scientists to explore. In this study, eight formulations of MOFs were synthesized and methane gas uptake was measured. The MOFs showed improved volumetric and gravimetric capacities. The ligands consisted mainly of dicarboxylic acids with an aromatic backbone. The biochemical processes through which MOFs exhibits toxicity was evaluated and shown to be consistent with that mitochondrial oxidative stress and associated cellular dysfunction that play key roles in disrupting oxygen consumption, energy production and generation of NO.)
