My chemistry teacher always showed that there was a greater complexity and understanding to be gained by asking the next question or going the extra step.
Pollution contributes to the death of some seven million people per year according to the World Health Organisation (WHO), and toxic gases such as nitrogen dioxide (NO2) and sulfur dioxide (SO2) are major contributing factors. Professor Schröder’s recent work has focused on the capture of these potent toxic gases that are emitted by industry, vehicles and shipping. By using the correct combination of metal centres and organic molecules that bridge those metal centres, new crystalline materials (called metal–organic frameworks) can be prepared that can act as sponges to selectively bind and store gases. The major challenge is that SO2 and NO2 are extremely caustic and reactive and many materials are simply not sufficiently stable to act as re-useable capture agents.
Professor Schröder’s recent materials are sufficiently stable, and he is now developing materials systems that can capture these toxic gases from the air, thus removing toxic emissions from the environment. His materials can be readily tuned by variations in pore size and shape and chemical functionality, and this approach is also applicable to the capture and separations of other gases such carbon dioxide, methane, hydrogen, ammonia, ethane, ethylene and acetylene.
