Hollow Co3O4 Mesoporous Structures with Predominantly Exposed (111) Planes for CO Oxidation

Abstract

The dual-walled characteristic mesoporous hollow structures of Co3O4 are explored as an efficient catalytic material for CO oxidation. The hollow structures with exposed (111) facets and a high surface area are attractive for efficient catalytic performance. As a result, complete CO conversion was achieved at 70 A degrees C and a conversion of about 90 % was maintained at 60 A degrees C for more than 600 min.
