Abstract

Nanocrystals of Co₃O₄ having different shapes (plates, rods, cubes, and spheres) were synthesized by using a hydrothermal method and their catalytic activities for CO oxidation were measured in dry reactant gas. The plate-like NCs mainly exposing {111} planes showed the highest catalytic activity among the four kinds of NCs.
