Abstract
Disclosed is a catalyst support for steam carbon dioxide reforming reaction utilizing the advantages of superior thermal conductivity and thermal dispersion of a metal foam support and a large specific surface area of a carrier material, which allows selective control of coating amount and the thickness of a support layer and prevents cracking on the support surface, using both the sol-gel method and the slurry method that have been used for coating of a metal foam support.
