An international team of scientists has developed a new material that can capture toxic nitrogen dioxide produced by burning fossil fuels and convert it into useful nitric acid just by using only water and air. The material, named MFM-520, can capture nitrogen dioxide at ambient pressure and temperature even at low concentrations and during flow in the presence of moisture, sulfur dioxide, and carbon dioxide. The team also used neutron spectroscopy and computational techniques to study the mechanism of adsorption of nitrogen dioxide in MFM-520. The post-treatment of nitrogen dioxide could lead to air pollution control and help to reduce the negative impact of nitrogen dioxide on the environment.
