摘要： A copper-palladium-loaded mesoporous silicon carbide-based catalyst, a preparation method, and an application thereof are provided. First, a mesoporous silicon carbide material is prepared by using mesoporous silica as a hard template; subsequently, the mesoporous silicon carbide material is mixed with a copper-palladium precursor mixed solution, and dried after the solvent is completely volatilized. The dried powder is successively subjected to calcination with N2 and reduction with H2 to finally obtain the copper-palladium-loaded mesoporous silicon carbide-based catalyst. The catalyst is made into an electrode, and the nitrate in water body is catalytically reduced by electrochemical method. The preparation method of the catalyst of the present invention is simple. The catalyst can realize high-efficiency catalytic denitrification at a low metal loading amount, with high selectivity of nitrogen. Moreover, the catalyst has the advantages of high activity, good stability, wide application range and low cost.

摘要： The present disclosure relates to the manufacturing and use of co-doped multi-metallic electrocatalysts for electroreduction of CO or CO2 to produce n-propanol. The co-doped multi-metallic electrocatalyst includes Cu as well as Ag and a secondary dopant, such as Ruthenium (Ru), Rhodium (Rh), Iridium (Ir), Palladium (Pd), Gold (Au) or Platinum (Pt). The co-doped multi-metallic electrocatalyst can be manufactured using a two-stage method where Cu nanoparticles are first doped with Ru and then doped with Ag. The co-doped multi-metallic electrocatalysts facilitate adsorption of CO, C1-C1 coupling, C1-C2 coupling and certain kinetics for the production of propanol by electroreduction with good selectivity at high current densities.

摘要： The present invention relates to a membrane-electrode assembly applied to a polymer electrolyte water electrolysis device (or system) that generates hydrogen and oxygen by electrolysis of pure water and to a polymer electrolyte water electrolysis stack comprising same. The present invention can accelerate entry into a hydrogen economy society by optimizing the compositions of an anode catalyst layer and a cathode catalyst layer among constituent elements of the membrane-electrode assembly to minimize the amount of a catalyst in the catalyst layers and reducing the power consumption to lower the production cost of hydrogen.
