Lessening atmospheric CO2

The potential of microporous materials known as feldspathoids to sequester carbon from the atmosphere has been studied by an Italian academic research group.
Lessening atmospheric CO2
The enormous amount of CO2 released into the atmosphere by the combustion of fossil fuels is a mounting environmental concern. As a means to combat this problem, many groups of scientists have concerned themselves with designing methods to permanently capture and store CO2. Common techniques are those that enhance carbonation of magnesium silicate minerals and inject supercritical CO2 fluids into corresponding geological strata.

Now however, data from an Italian academic research group claims that feldspathoid minerals can provide another alternative means to sequester CO2. Feldspathoids are microporous materials characterised by various structural cages and channels that host cations and anionic species. In-situ high-temperature Fourier Transform Infrared (FTIR) experiments show that the different species have significantly different thermal behaviour regarding volatiles.

Furthermore, since feldspathoids are naturally widespread across several areas of the world, they can be an alternative method of storing CO2 to cope with Kyoto agreement requirements. This new method is also less expensive and less time consuming. The research group extends its know-how to companies or research centres involved in environmental monitoring or production of new materials for pollution control.
