Scientists in Ireland have invented a new sponge material able to absorb toxic benzene from polluted air.
Benzene is classified as a carcinogen that increases the risk of cancer and other illnesses and is also a cause of bone marrow failure.
Professor Michael Zaworotko, Bernal chair of Crystal Engineering and Science Foundation of Ireland research professor at University of Limerick’s Bernal Institute.The material is capable of capturing even trace amounts of benzene from the air, and crucially uses less energy than existing materials to do so, according to the researchers.
Zaworotko explained,"A family of porous materials - like sponge - have been developed to capture benzene vapor from polluted air and produce a clean airstream for a long working time." In terms of energy, because the capture process is based upon physical rather than chemical bonding, the energy footprint of capture and release is much lower than previous generations of materials.
The water harvesting material has favorable properties for capturing and releasing water from the atmosphere that is already being used in dehumidification systems.

Synthesis of γ-graphyne using dynamic covalent chemistry - Nature SynthesisThe synthesis of graphynes has often been limited to using irreversible coupling reactions that are likely to result in materials that lack long-range order. Now, a periodically sp–sp2-hybridized carbon allotrope, γ-graphyne, is prepared using a reversible dynamic alkyne metathesis and managing the balance between kinetic and thermodynamic control. This material’s interlayer stacking and folding behaviour are also revealed.
