Molybdenum nitride were prepared by temperature programming gas solid reaction of ammonia with molybdenum trioxide. Reaction products have been investigated and studied by means of X ray diffraction and solution adsorption,and experimental results show that reaction temperature, preparation method and preparation condition have the important influence on crystallization phases and crystalline distribution. The molybdenum nitride with high specific surface area has been prepared, and molybdenum nitrides electrode behaves good character.
