Scientists in Germany and Canada have developed a new way to capture sulfur dioxide gas. It could minimise the environmental impact of the gas, which causes acid rain.
The team made a series of frustrated Lewis pairs (FLPs) consisting of a bulky phosphane Lewis base component and a boron Lewis acid component. The FLPs rapidly and efficiently trap sulfur dioxide by adding the phosphane component to sulfur and the boron to oxygen.
