A new record was recently presented by scientists at TU Dresden, a novel material named DUT-9 (Dresden University of Technology No. 9). The nanoporous material contains an enormous number of small pores leading to the highest ever observed CO2-stroage capacity of 1.64 g/g CO2 in the field of porous solids [1]. Such a high storage capability is caused by the high specific surface area and pore volume (2.18 cm3g-1), surpassing that of established adsorbents (activated carbon, zeolites) significantly.

Nanoporous materials are used in air purification and for the separation of toxic gases. CO2-separation is also a crucial requirement for the purification of environmentally friendly biogas, before injecting biogas into the fuel supply chain.

The novel material DUT-9 belongs to the so called “Metal-Organic Frameworks”, a new class of porous solids studied at TU Dresden in the scope of the DFG priority program MOFs (SPP 1362) coordinated by Prof. Kaskel.
