A solid composition is prepared by mixing water, a hydraulic cement, aluminum metal powder, and a catalyst composition comprising (a) an inorganic support, (b) Pt and/or Pd metal (c) and Fe metal and/or oxide, followed by maintaining the obtained mixture under such conditions as to affect hardening of the hydraulic cement. Preferably, the hydraulic cement is a Type III portland cement and/or a Class H well cement. The thus-prepared solid compositon can be used as a CO oxidation catalyst. |
