CO2吸附材料正在研制中

A novel porous¹（多孔渗水的） material that has unique carbon dioxide retention²（保留） properties has been developed through research led by The University of Nottingham. The findings, published in the peer-reviewed journal Nature Materials, form part of ongoing³ efforts to develop new materials for gas storage applications and could have an impact in the advancement⁴ of new carbon capture products for reducing emissions⁵ from fossil fuel processes.

#

It focuses on the metal organic framework NOTT-202a, which has a unique honeycomb-like structural⁶ arrangement and can be considered to represent an entirely⁷ new class of porous material. #

Most importantly, the material structure allows selective adsorption of carbon dioxide -- while other gases such as nitrogen, methane⁸ and hydrogen can pass back through, the carbon dioxide remains⁹ trapped in the materials nanopores, even at low temperatures. #

Unique material

Lead researcher Professor Martin Schröder, in the University's School of Chemistry, said: "The unique defect structure that this new material shows can be correlated directly to its gas adsorption properties. Detailed¹⁰ analyses via structure determination and computational modelling have been critical in determining and rationalising the structure and function of this material." #

The research team -- which is included Dr Sihai Yang, Professor Alexander Blake, Professor Neil Champness and Dr Elena Bichoutskaia at Nottingham -- collaborated¹¹ on the project with colleagues at the University of Newcastle and Diamond Light Source and STFC Daresbury Laboratory.

NOTT-202a consists of a tetra-carboxylate ligands -- a honeycomb like structure made of a series of molecules¹² or ions bound to a central metal atom -- and filled with indium（铟） metal centres. This forms a novel structure consisting of two interlocked frameworks.

Innovative¹³ solutions #

State-of-the-art X-ray powder diffraction measurements at Diamond Light Source and advanced computer modelling were used to probe and gain insight into the unique carbon dioxide capturing properties of the material.

#

The study has been funded by the ERC Advanced Grant COORDSPACE and by an EPSRC Programme Grant ChemEnSus aimed at applying coordination¹⁴ chemistry to the generation of new multi-functional porous materials that could provide innovative solutions for key issues around environmental and chemical sustainability.#p#分页标题#e# #

These projects incorporate multi-disciplinary collaborations across chemistry, physics and materials science, and aim to develop new materials that could have application in gas storage, sieving¹⁵ and purification, carbon capture, chemical reactivity and sensing.
