Chemistry
World: Researchers in the US
have
shown that perovskites—a class of mixed oxide
minerals—can perform as well as platinum in certain types
of catalytic converter for removing pollutants from diesel
exhaust. Although it is early days in the research, the finding
could eventually result in cheaper, more robust catalytic
converters for diesel engines that do not rely on expensive and
scarce platinum group metals.
