摘要： A low-platinum catalyst based on nitride nanoparticles and a preparation method thereof. A component of an active metal of the catalyst directly clades on a surface of nitride particles or a surface of nitride particles loaded on a carbon support in an ultrathin atomic layer form. Preparation steps including: preparing a transition-metal ammonia complex first, nitriding the obtained ammonia complex solid under an atmosphere of ammonia gas to obtain nitride nanoparticles; loading the nitride nanoparticles on a surface of a working electrode, depositing an active component on a surface of the nitride nanoparticles by pulsed deposition, to obtain the low platinum loading catalyst using a nitride as a substrate. The catalyst may be used as an anode or a cathode catalyst of a low temperature fuel cell.

摘要： Disclosed are a method and device for using CO2 mineralization to produce sodium bicarbonate or sodium carbonate and output electric energy. The device comprises an anode area, an intermediate area, and a cathode area. The anode area and the intermediate area are spaced by a negative ion exchange membrane (2). The intermediate area and the cathode area are spaced by a positive ion exchange membrane (3). The anode area, the intermediate area, and the cathode area can accommodate corresponding electrolytes. An anode electrode (1) is disposed in the anode area, a cathode electrode (4) is disposed in the cathode area, and the cathode electrode and the anode electrode are connected through a circuit. A raw material hydrogen gas inlet is disposed in the anode area, and a CO2 inlet and a product hydrogen gas outlet are disposed in the cathode area. The method is based on the principle of CO2 mineralization and utilization, combines the membrane electrolysis technology, facilitates spontaneous reaction by using the acidity of CO2 and the alkalinity of the reaction solution and realizes separation of the products, and converts through a membrane electrolysis apparatus the energy released by the reaction into electric energy at the same time when producing the sodium bicarbonate or sodium carbonate and outputs the electric energy. The method and device have low energy consumption, high utilization rate of raw materials and little environmental pollution, and can output electric energy while producing sodium carbonate at the same time.
