Elucidation on the degradation mechanism of nanoporous catalysts at the atomic level

Preventing degradation by crystallographic defects toward enhancing performance

Summary

A research group led by Associate Professor Takeshi Fujita and Professor Mingwei Chen of the Advanced Institute for Material Research at Tohoku University with the High Voltage Electron Microscope Laboratory at Nagoya University elucidated the mechanism of nanostructure coarsening and degradation in nanoporous catalysts, a promising catalyst in automobile exhaust purification. The research group also elucidated the atomic level mechanism that prevents degradation by introducing crystallographic planar defects.
