Scientists have created molecular cages within a polymer to trap harmful sulphur dioxide pollution in order to transform it into useful compounds and reduce waste and emissions.

A unique new material developed by an international collaboration of scientists has proved that it can help reduce sulphur dioxide (SO2) emissions in the environment by selectively catching the molecules in minutely engineered cages. The captured toxic gas can then be safely released for conversion into useful industrial products and processes.

% - Sulphur - Dioxide - Emissions - Result

Around 87% of sulphur dioxide emissions are the result of human activity, typically produced by power plants, other industrial facilities, trains, ships, and heavy equipment, and can be harmful to human health and the environment. The international team developed porous, cage-like, stable copper-containing molecules known as molecular organic frameworks (MOFs) that are designed to separate sulphur dioxide (SO2) gas from other gases more efficiently than existing systems.

Professor Martin Schröder, Vice-President and Dean of the Faculty of Science and Engineering at the University of Manchester, and Dr. Sihai Yang, a Senior Lecturer in Department of Chemistry at the University of Manchester, led an international research team from UK and U.S. on this work.

The researchers exposed the MOFs to simulated exhaust gases and found that they efficiently separated out SO2 from the gas mixture at elevated temperatures even in the presence of water.
