Preparation method of electrode material for high-selectivity recovery of ammonia
The invention discloses a preparation method of an electrode material for high-selectivity recovery of ammonia, and the preparation method of the electrode material mainly comprises the following steps: mixing a nickel source, a cobalt source and a precipitant into deionized water and an organic solvent according to a ratio through an in-situ growth method, and fully stirring to obtain a precursor; the precursor and the load substrate are subjected to dissolution reaction at high temperature and high pressure and then calcined, so that the precursor grows on the substrate in situ, and the electrode material with the local electric field enhancement function is formed. The preparation method of the electrode material can be used for recycling sulfur and nitrate resources in the flue gas desulfurization and denitrification absorption liquid, the selectivity of recycling the nitrate resources into ammonia is improved, and recycling of ammonia energy can be achieved..
