摘要: Nitrogen co-doping with ruthenium mesoporous carbons (Ru–N-MC) was prepared by co-impregnation of sucrose and urea on a RuCl3/SiO2 template followed thermal carbonization process. The turnover frequency (TOF) the Ba/Ru–N-MC catalyst in ammonia synthesis is 0.16 s−1 under reaction conditions 400 °C, pressure 10 MPa space velocity 10 000 h−1. superior catalytic performance proposed to originate from strong metal-support interaction between Ru nanoparticles (NPs) carbon support. In addition activity, exhibits long-term stability for 35 h without significant deactivation.
