Natural gas could bridge gap from gasoline to electricvehicles, thanks to metal-organicframeworks umich angew_chem angew_chem
Natural gas could be a viable alternative. It's widely available and burns more cleanly than gasoline. There are even conversion kits already available to allow your passenger cars or long-haul trucks to run on natural gas, says Adam Matzger, professor of chemistry at the University of Michigan.
Matzger worked with Alauddin Ahmed, assistant research scientist in mechanical engineering at the U-M College of Engineering, to scan nearly one million MOFs that have already been developed to find materials that might have the right characteristics to store methane. They found two that had not been previously tested, one of which had coincidentally been created in Matzger's lab.
"The idea is by having an adsorbent in a tank, you can store more methane at lower pressures than you could without the absorbent because it helps to hang on to the methane at lower pressures," Matzger said."So then the problem comes down to picking an adsorbent, and this is where the theory really came to the rescue."
Ahmed used two different methods to screen for two different classes of MOFs. One class of MOFs have what's called a closed metal site. Another other class of MOFs was found to have an open metal site, but only once the researchers computationally scrubbed water molecules from within the structure of these MOFs.
