Polycrystalline-iron-loaded porous biochar aerogel catalyst and preparation method and application thereof

Abstract

The present invention discloses a polycrystalline-iron-loaded porous biochar aerogel catalyst and a preparation method and application thereof, and pertains to the field of preparation of carbon catalysts. The polycrystalline-iron-loaded porous biochar aerogel catalyst in the present invention comprises a porous biochar substrate. Polycrystalline iron nanoparticles are loaded on biochar layers through Fe—C bonds, and the porous biochar aerogel has an internal structure that is an overall honeycomb-like porous network structure. The preparation method of the catalyst in the present invention utilizes ion exchange of crosslinking agents to crosslink iron-based materials with carbon-based materials, and accomplishes the preparation through treatments of freeze-drying and high-temperature calcination.
