Discovery could improve natural gas storage

Posted by Lauren Steadman

Scientists have made a discovery that could transform natural gas storage for the oil industry.

In a study published by journal Nature Chemistry, a Northwestern University research team noted that porous crystals called metal-organic frameworks make ideal materials for natural gas storage due to their nanoscopic pores and high surface areas.

However, as investigation into the millions of different structures possible would be time-consuming, the researchers have created an algorithm that automatically generates and tests hypothetical metal-organic frameworks (MOFs), singling out the ones with the most potential.

"When our understanding of materials synthesis approaches the point where we are able to make almost any material, the question arises: Which materials should we synthesize?" said Randall Q Snurr, professor of chemical and biological engineering in the McCormick School of Engineering and Applied Science.

He added that the study provides a powerful method to answer that query.

MOFs are not restricted to use in gas storage and as cleaner fuel, as their discovery potentially leads the way to better drug delivery, chemical sensors and carbon capture.
