▎ 摘　　要

NOVELTY - Fuel gas infrared catalytic fiber layer comprises a graphene surface layer and an alumina catalytic layer. The alumina catalytic layer adopts a platinum-doped activated alumina fiber layer, and the graphene surface layer is formed by mixing graphene and alumina. USE - Fuel gas infrared catalytic fiber layer. ADVANTAGE - The fuel gas infrared catalytic fiber layer has flocculation effect of aluminum hydroxide itself to disperse platinum hydroxide staggeredly, and use water vapor to open the gap in the process of water loss to form a uniform microporous structure. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a gas infrared catalytic combustion device, which comprises a fuel gas layer, a pre-heating layer and the catalytic fiber layer which are arranged in sequence from the inside to the outside, and the catalytic fiber layer includes a graphene surface layer and an alumina catalytic layer. The lower surface of the alumina catalyst layer is connected with the preheating layer, and the upper surface is connected with the graphene surface layer.
