Preparing method of transition metal-nitrogen doped porous carbon catalyst

摘要

The present invention relates to a process for preparing a slurry by mixing a precursor containing carbon, a transition metal and nitrogen, a silica template and a solvent (first step); Heating the slurry to evaporate the solvent to form a powdery composite (second step); Carbonizing the composite by heating under an inert gas, and cooling the composite to form crystalline carbon (the third step); And a step of washing the crystalline carbon with an acid to form a porous carbon catalyst (fourth step), and a porous carbon catalyst prepared by the method. The porous carbon catalyst doped with the transition metal and nitrogen does not use an expensive platinum catalyst and is easily produced in a one-pot process by using a precursor containing both carbon, transition metal and nitrogen, The carbon catalyst of a thin thickness can be formed by using the precursor of the fuel cell, thereby increasing the economical efficiency of the fuel cell manufacturing process and greatly increasing the reduction characteristic of the cathode electrode of the fuel cell.
