Abstract
Disclosed is a ruthenium-based catalyst for ammonia synthesis, preparation method and use thereof. The ruthenium-based catalyst comprises Ru—Ba-A core-shell structure which comprises a ruthenium nanoparticle as a core covered with a first shell and a second shell sequentially, wherein the first shell consists of a barium nanoparticle, and the second shell consists of a metal oxide. The Ru—Ba-A core-shell structure can effectively preventing agglomerations of ruthenium nanoparticles during the use of the catalyst and avoiding direct contact between the ruthenium nanoparticles and the metal oxides. In addition, barium nanoparticles have a promoting effect as an electronic promoter, which can effectively improve the stability and catalytic activity of ruthenium-based catalyst for ammonia synthesis, especially in the system for synthesizing ammonia from a coal gas.
An ammonia fuel cell system and an electric device are described. The ammonia fuel cell system includes an ammonia decomposition reaction device, a heating device, a hydrogen fuel cell, a DC/DC converter and an inverter connected successively, a battery pack and a heat exchanger. The heat exchanger of the system, can preheat ammonia gas by energy generated by ammonia decomposition, thereby recycling heat waste. The battery pack supports a quick response and stable output to quickly cope with the acceleration and deceleration of the electric device. This improves the stability of the system operation, and electric energy generated by the hydrogen fuel cell or electric energy in the battery pack can be transferred to the outside. The battery pack or the heating device can provide energy to the ammonia decomposition reaction device, so there is no need to supply outside energy to the ammonia decomposition reaction device.
