Abstract
This invention belongs to the field of catalyst support technology and discloses a metal oxide nano-island confined support, its preparation method and application. Based on a specific metal salt, this invention proposes a specific pH adjustment method and calcination conditions. The process is simple, requires no additional additives, and can produce nano-island supports with small and uniform average particle size and mutual isolation. The metal oxide nano-island confined support is rich in oxygen vacancies and can be used to load noble metal single atoms, which is beneficial to improving the performance of catalysts.
