| titleOfInvention | A kind of N doping graphitise diamond and preparation method |
| abstract | A kind of N doping graphitise diamond, it is a kind of with diamond for core, and N doping graphite linings is the core-shell composite material on top layer. The diamond of 5～100nm mainly under vacuum conditions, is carried out 1200～1600 DEG C of heat treatments of 30～60min so that it is graphitization occurs in top layer by the preparation method of above-mentioned N doping graphitise diamond; Again graphitise diamond is placed in the mixed solution of concentrated sulphuric acid and concentrated nitric acid, under room temperature environment, it is carried out the corrosion treatmentCorrosion Science of 24～48h, obtain the graphitise diamond of oxidation, it is mixed with nitrogenous source, and the heat treatment carrying out 800～1300 DEG C in a nitrogen environment can prepare N doping graphitise diamond. The present invention will not make remaining magnesium-yttrium-transition metal in diamond, there is the electrochemical stability of excellence, prevent the inactivation of the catalyst caused because of electrochemically stable difference, oxygen reduction reaction is had good catalysis activity by N doping graphite linings, can the expensive platinum based catalyst of fictitious hosts, be applied to the negative electrode of fuel cell. |
