▎ 摘　　要

NOVELTY - Device comprises an anode electrolytic cell, a cathode electrolytic cell and a top closed sulfuric acid washing tank. The anode electrolytic cell is provided with a cobalt phosphate catalyst. The cathode electrolytic cell is provided with a single central uranium-based load catalyst. The cathode electrolytic cell is provided with a nitrogen inlet pipe. The cathode electrolytic cell and sulfuric acid washing tank is provided with connecting pipe between. The one end of connecting pipe is located above liquid level of cathode electrolytic cell, and the other end is located below liquid level of sulfuric acid washing tank. USE - The device is for preparing ammonia by continuous flow electrocatalysis synthesis (claimed). ADVANTAGE - The method: enriches ammonia in catholyte and sulfur pickling tank, which realizes normal temperature, green, and continuous electro-reduction of nitrogen and ammonia collection process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing ammonia by continuous flow electrocatalytic synthesis, comprising (i) preparing single-site uranium-based supported catalysts by adsorbing uranyl ions in simulated nuclear waste liquid by nitrogen-doped graphene, graphene oxide and reduced graphene oxide, (ii) preparing oxygen evolution cobalt phosphate catalyst, and (iii) using cobalt phosphate catalyst as anode, and using single-center uranium-based supported catalyst as cathode, introducing nitrogen into catholyte to catalyze synthesis of ammonia and collect it by washing with sulfuric acid. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of device.
