Porous ceramic as well as preparation method and application thereof
The invention discloses a porous ceramic which comprises a silicon carbide porous ceramic matrix, wherein a silicon carbide film is attached to the surface of the hole wall of the silicon carbide porous ceramic substrate; nanometer nickel particles are embedded in the silicon carbide film. The invention also discloses a catalytic micro-reactor and a catalytic micro-reaction system comprising the porous ceramic, and a preparation method of the catalytic micro-reactor. The porous ceramic can reduce the reaction space and contribute to realizing miniaturization of a reforming hydrogen productionsystem; in addition, the nano nickel particles are embedded in the silicon carbide film to improve the bonding strength of catalyst loading and contribute to realizing vehicle-mounted online hydrogenproduction.
本发明公开了一种多孔陶瓷，包括碳化硅多孔陶瓷基体；所述碳化硅多孔陶瓷基体的孔壁表面附着有碳化硅薄膜；所述碳化硅薄膜中镶嵌有纳米镍颗粒。本发明还公开了一种包括所述多孔陶瓷的催化微反应器和催化微反应系统，以及所述催化微反应器的制备方法。所述多孔陶瓷可减小反应空间，有助于实现重整制氢系统的小型化，纳米镍颗粒镶嵌于碳化硅薄膜中可提高催化剂负载的结合强度，有助于实现车载在线制氢。
