TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preparation: The preparation method for non-Au load type catalyst for catalyzing and oxidizing CO at room temperature comprises (1) loading CoB amorphous alloy at oxide carrier, to prepare the intermediate of CoB amorphous alloy; and (2) loading the active ingredient Pt at the intermediate prepared in (1), to prepare the load type catalyst with CoB and Pt. Preferred Process: In (1), putting the formed oxide or powder oxide carrier in the cobalt(II) sulfate (CoSO4) solution to dip for 1-24 hours, after filtering the solution, drying at 60-120 degrees C, sintering for 1-4 hours at 100-300 degrees C in nitrogen gas (N2) gas; putting the sintering material in the sodium borohydride (NaBH4) solution including sodium hydroxide (NaOH), stirring for 2-8 hours at room temperature, to fully react with cobalt (Co), after eliminating the ion with the de-ionized water, drying at 60-120 degrees C to prepare the intermediate of the CoB amorphous alloy. In (2), putting the intermediate of the CoB amorphous alloy prepared in (1) in the hydrogen platinum(IV) chloride HPtCl4 acid solution, dipping for 1-8 hours, after filtering the solution, drying at 60-120 degrees C, putting the dried material in the NaBH4 with NaOH, stirring for 2-8 hours at room temperature, after eliminating the ion with the de-ionized water, drying at 60-120 degrees C to obtain the load type catalyst with CoB amorphous alloy and Pt. Preferred Composition: The Pt content of the active ingredient in the catalyst is 0.5-5.0 wt%, CoB amorphous alloy content is 0.5-5.0wt.%, and the residual component is the oxide carrier. The weight ratio of CoSO4 solution and oxide carrier is 1/1-5/1; the CoSO4 content of CoSO4 solution is 0.1-1.0mol/L; the weight ratio of the NaBH4 solution with NaOH and sintering material is 1/1-5/1, the content of the NaOH of the NaBH4 with NaOH is 0.05-0.5mol/L. The concentration of HPtCl4 acid solution is 0.02-0.20mol/L; the weight ratio of NaBH4 solution with NaOH and intermediate of CoB amorphous alloy is 1/1-5/1; the NaOH content of the NaBH4 solution is 0.05-0.5mol/L.
