Porosity Local Analysis (PoLA): A New Approach to Describe the Porous Volume Distribution in Amorphous Carbons.

ABSTRACT: A new procedure, named PoLA (Porous Local Analysis), is presented to describe the porosity of amorphous carbons accurately. Unlike models based on predefined geometrical pores, PoLA is based on a point-by-point description of the inner void, and it is particularly suitable for amorphous materials. The porous volume is partitioned into small elements (blocks) of user-defined size, and each block is assigned a micro-, meso-, or macroporous nature according to its minimum distance from the material walls. This method is very fast and characterizes any porous volume uniquely: most importantly, this distribution of volume allows one to predict the gas adsorption behavior of the material. To show this, a number of carbon models have been defined, spanning a large range of porosities, and the ads
