Pore Chemical Modification of Bimetallic Coordination Networks for Coal-Bed Methane Purification under Humid Conditions.

The recycling of low-concentration coal-bed methane (CBM) is environmentally beneficial and plays a crucial role in optimizing the energy mix. In this work, we present a strategy involving pore chemical modification to synthesize a series of bimetallic diamond coordination networks, namely CuIn(ina), CuIn(3-ain), and CuIn(3-Fina) (where ina = isonicotinic acid, 3-ain = 3-amino-isonicotinic acid, and 3-Fina = 3-fluoroisonicotinic acid). Among these, the amino-functionalized CuIn(3-ain) exhibits excellent CH adsorption capacity (1.

Amino-Functionalized Microporous MOFs for Capturing Greenhouse Gases CF and NF with Record Selectivity.

The capture and separation of fluorinated gases (F-gases) from N has the potential to not only reduce greenhouse gas emissions but also provide economic benefits for the semiconductor industry. In this work, two Ni-based metal-organic frameworks (MOFs), (Ni(ina), ina = isonicotinic acid) and amine-functionalized (Ni(3-ain), 3-ain = 3-aminoisonicotinic acid), were constructed for capturing F-gases (CF and NF). At ambient conditions, both materials exhibit very high CF sorption capacities (2.
