New Findings from Monash University in Nanoporous Provides New Insights

May 16, 2014



By a News Reporter-Staff News Editor at Science Letter -- Researchers detail new data in Nanoporous. According to news reporting originating from Clayton, Australia, by NewsRx correspondents, research stated, "The carbonization of a newly reported two-dimensional zeolitic imidazolate framework (ZIF-L) with leaf-like morphology was investigated by TG, SEM, XRD and XPS. ZIF-L flakes were thermally stable at up to 200 degrees C, and completely transformed into an amorphous carbonaceous material after heat treatment in nitrogen at 550 degrees C. A carbon composite membrane was then prepared by deposition of ZIF-L flakes on a porous alumina support and then direct carbonization of ZIF-L film."

Our news editors obtained a quote from the research from Monash University, "During the carbonization, the ZIF-L membrane reorganized into a nanoporous carbon composite membrane composed of ZnO nanoparticles and leaf-like carbon flakes. The resulting nanoporous carbon composite membrane exhibited a narrow micropore size distribution, and it had higher BET surface area than the ZIF-L flakes. Gas separation permeation experiments showed that the carbon composite membrane had a high H-2 permeance of 3.5 x 10(-6) mol m(-2) s(-1) Pa-1, and moderate H-2/N-2 and H-2/CO2 ideal selectivities of 6.2 and 4.9, respectively."

According to the news editors, the research concluded: "This work presents a simple and effective method for preparing functional nanoporous carbon composite membranes from ZIFs (or MOFs) for many potential applications."
