This research has been carried out between Pablo de Olavide University and the University of Granada and it shows how the modification of synthetic porous solids (metalorganic network type) leads to a significant improvement in the capture of polluting gases from the combustion of fossil fuels through the creation of crystalline defects.
Specifically, researchers at these universities have studied the capture of sulfur dioxide in defective networks of nickel pyrazolates exchanged with barium ions as a consequence of specific interactions between the contaminating gas molecules and the crystal defects.
Emissions of toxic gases from fossil fuel combustion represent high risks to the health of people worldwide. In this regard, the World Health Organization (WHO) suggests that poor air quality is directly responsible for one-eighth of global total deaths. Therefore, developing efficient technologies to capture toxic gases from static sources (power plants) and mobile (vehicles) is a critical project for environmental sustainability.
The main discovery of this research is the conclusion that the elimination of sulfur dioxide in emissions from thermal power plants can reduce environmental problems such as acid rain.
This research has been carried as a part of several projects (Marie Curie, European Research Council and MINECO Challenges) which count with the participation of scientists from both universities, Pablo de Olavide and Granada.
Jorge A. Rodríguez Navarro, L. Marleny Rodríguez-Albelo and Elena López-Maya work for the Inorganic Chemistry Department of the University of Granada. On the other hand, Sofía Calero leads the Nanostructured Materials Group for Technological Applications of the Department of Physics, Chemistry and Natural Systems at Pablo de Olavide University. In this group, the use of molecular simulations is studied for the development of new multifunctional materials for applications in basic science and technology. In this research, Calero has worked with Said Hamad and A. Rabdel Ruiz-Salvador.
