Reports Outline Nanoporous Findings from University of Toronto

May 16, 2014

By a News Reporter-Staff News Editor at Science Letter -- Researchers detail new data in Nanoporous. According to news reporting out of Toronto, Canada, by NewsRx editors, research stated, "Nanoporous carbon materials have a wide range of applications in environmental and sustainable energy fields. Accurate quantification of micropores (

Our news journalists obtained a quote from the research from the University of Toronto, "To quantify micropores in carbon materials, the gas physisorption technique remains the most common. Despite its long history and popularity, the technique is still developing due to the recent progress in applying density functional theory (DFT) models to physisorption. Because of the complex nature of DFT, it remains a challenging task to accurately characterize porous structures of nanoporous carbons. In this work we use four distinct carbon samples and quantify the uncertainties associated with the DFT models. We demonstrate that more accurate interpretation of pore sizes in nanoporous carbons can be achieved by selecting the appropriate DFT kernels and adsorbates. We propose a procedure that joins two sets of pore size distribution (PSD) data provided by application of two DFT models (non-local DFT and quenched solid DFT) while using two adsorbates (N-2 and CO2), respectively."

According to the news editors, the research concluded: "It is hoped that this paper will serve as a practical guide for researchers who use the gas physisorption technique and consider adopting the DFT model."
