Zeolite crystals are used in the manufacture of countless products today, which utilize their properties of absorption, ion exchange, and catalysis. It was determined that zeolites grown in space could be much larger in size than any of those currently available on Earth. The objective was to identify and examine some of the potential uses for these larger crystals.

The zeolite crystals grown on the ground, left, are smaller than ones grown in space, right. If larger, more perfect crystals can be grown, researchers learn more about the way zeolites are made. This information might be used to improve petroleum processing and reduce costs and pollution.

Achieving control over the morphology of zeolite crystals at the nanoscale is crucial for enhancing their performance in diverse applications including catalysis, sensors and separation. The complexity and sensitivity of zeolite synthesis processes, however, often make such control both highly empirical and difficult to implement. We demonstrate that graphene can significantly alter the ...
