The carbon foam is a functional material having a three-dimensional network structure . In addition to the regular performance of the carbon material , carbon foam also has a unique pore structure , high thermal conductivity , high conductivity , a large contact area , low-density and low expansion characteristics that makes the carbon foam in the chemical , aerospace , electronics and many other fields have a wide range of applications . In this paper, the mesophase pitch as raw material , the use from regular foam preparation pore structure with high mechanical strength of carbon foam and explored its application in the field of denitrification . First, by dispersing an appropriate amount of reinforcement , such as carbon nanotubes , carbon microspheres in the mesophase pitch , and enhance the mechanical properties of the carbon foam ; Secondly, high - strength carbon foam as a carrier , an ethylene as a carbon source , the nickel catalyst , vapor-grown carbon foam surface synthesis of uniform nano-carbon fiber layer synthetic CNFs - carbon foam catalyst carrier ; Finally, preliminary explore MnOx-CeO2/CNFs- carbon foam in the field of denitrification . The main results are as follows : 1 ) the use of mechanical agitation - ultrasound method of dispersing carbon nanotubes ( CNTs ) can be uniformly dispersed in the mesophase pitch-based body . Its as raw materials , the use of self- foaming method , prepared under the conditions of 600 ° C / 3 MPa foam compression strength of 3.14 MPa , the compression modulus of 4.33 MPa of carbon foam . 2 ) Ni catalyst using chemical vapor deposition technique , the growth of carbon nanofibers ( CNFs ) bore wall surface of the carbon foam , prepared the CNFs - carbon foam of high specific surface area . The carbon foam pretreatment , catalyst loading , drying method and time of growth CNFs growth had significant effects . Under the conditions of 500 ° C , 200ml/min total amount of the gas CNFs average diameter of 20nm, a length of 2 - 5μm , the the CNFs - carbon foam specific surface area of 70.23m2 / g . 3 ) In CNFs - carbon foam as the carrier , MnOx - CeO2 catalysts investigated the catalytic activity of the catalyst for NOx removal . Wherein the catalyst at 180 to 220 ° C temperature zone , denitrification efficiency higher than 90%.
