Abstract

The invention discloses a macroporous carbon base material for adsorbing environmental carbon monoxide and a preparation method of the macroporous carbon based material. The method comprises steps asfollows: (1) pretreating activated carbon particles; (2) preparing a soluble iron salt solution;(3) performing impregnation; (4) performing ultrasonic treatment; (5) performing drying; (6) performingcalcination; (7) adding activated carbon particles with iron oxide attached after calcination to an acid solution, performing ultrasonic impregnation for 1-5 h, then, washing the obtained mixture to be neutral with deionized water, placing the mixture to an oven for drying at 60-120 DEG C for 15 h to obtain the macroporous carbon based material. Thus, the problem that activated carbon adopts a macroporous structure in the prior art is solved.

Description

technical field [0001] The invention belongs to the field of material preparation, in particular to the field of preparation of macroporous adsorption materials, in particular to a macroporous carbon-based material for adsorbing ambient carbon monoxide and a preparation method thereof. Background technique [0002] The harm of carbon monoxide to humans and the environment is well known, and the elimination of carbon monoxide has become one of the hotspots of green chemistry research. Therefore, the research on materials for efficient adsorption of carbon monoxide is becoming more and more extensive, and it has high practical value in air purifiers, gas sensors, closed one-cycle lasers, gas masks, and elimination in closed systems. In addition, a small amount of carbon monoxide gas is mixed in the fuel cell's energy oxygen, which has a poisonous effect on the fuel cell catalyst. Therefore, it is necessary to selectively adsorb carbon monoxide in the mixed gas. It can be seen ...
