Methane gobbling material found, scientists say

Scientists have discovered a new material that can capture and concentrate methane, a potent greenhouse gas.

While carbon dioxide, the most abundant greenhouse gas, can be captured using a variety of techniques, methane capture has proved elusive primarily because it interacts weakly with other materials, according Amitesh Maiti, a researcher at the Lawrence Livermore National Laboratory.

He and colleagues discovered that various forms of zeolites, which are commonly used in water purification and other industrial processes, appear well-suited for the task. That’s because the material’s crystalline structure can be fine-tuned for various gas separation or storage applications, he explained.
