Cobalt catalyst and preparation method thereof

Abstract

A cobalt catalyst and a preparation method thereof are provided. The cobalt catalyst includes a carrier and a catalytically active substance; the carrier is a cobalt-based substrate material; the catalytically active substance is grown on the surface of the carrier, and the catalytically active substance has a morphology of hydrangea-shaped nanospheres. The cobalt catalyst is an autogenously grown monolithic nanosphere catalyst with a three-dimensional structure assembled by nano-sheets on the catalyst surface. The cobalt catalyst has a high specific surface area and can fully expose the catalytically active sites to enhance the catalytic efficiency. Compared to a nanowire catalyst, the cobalt catalyst has better self-supporting properties, and the active components are not easily aggregated nor fall off during a use process. Therefore, the cobalt catalyst has a longer service life.
