主 题:Hydrogenation Nitro compounds Two-dimensional sheets Heterojunction Nitrides
摘 要:Hydrogenation reactions play crucial roles on chemical synthesis and pollutant *** improvement of the ability to activate reactants and increase of the contact probability between the catalysts and reactants are positive to improve the catalytic ***,we have reported the design of two-dimensional porous Ni-Ni_(3)N-Ni Mo N heterojunction sheets(2D Mo-Ni based nanosheets)for efficient catalytic hydrogenation of the aromatic *** heterojunction interfaces provide plentiful active sites to improve the activating ability of the catalyst on the ***,the 2D porous structure facilitates not only the contact of catalytic sites with reactants but also mass transfer and diffusion,both of which are favorable to accelerating the hydrogenation *** a result,the optimized sample of 2D Mo-Ni sheet exhibits good activity for the hydrogenation of aromatic nitro-compounds by converting 0.2 mmol/L(30 mL)of p-nitrophenol to p-aminophenol within 45 s with good *** activation energy and the reaction rate at 25℃ is 31.11 k J/mol and 0.0796 s^(-1),respectively,both of which surpass most of reported non-noble metal catalysts and rivals with most noble metal-based *** combination of late and early transition metals provides an innovative way to obtain outstanding catalysts for the hydrogenation.
