摘　　要：Electrocatalytic NO reduction reaction offers a sustainable route to achieving environmental protection and NH3 production targets as well.In this work,a class of dealloyed Ti_(60)Cu_(33)Mn_(7)ribbons with enough nanoparticles for the high-efficient NO reduction reaction to NH_(3)is fabricated,reaching an excellent Faradaic efficiency of 93.2%at–0.5 V vs reversible hydrogen electrode and a high NH_(3) synthesis rate of 717.4μmol·h^(-1)·mg_(cat).^(-1) at–0.6 V vs reversible hydrogen electrode.The formed nanoparticles on the surface of the catalyst could facilitate the exposure of active sites and the transportation of various reactive ions and gases.Meanwhile,the Mn content in the TiCuMn ribbons modulates the chemical and physical properties of its surface,such as modifying the electronic structure of the Cu species,optimizing the adsorption energy of N^(*)atoms,decreasing the strength of the NO adsorption,and eliminating the thermodynamic energy barrier,thus improving the NO reduction reaction catalytic performance.Moreover,a Zn-NO battery was fabricated using the catalyst and Zn plates,generating an NH_(3) yield of 129.1µmol·h^(-1)·cm^(-2)while offering a peak power density of 1.45 mW·cm^(-2).
