Ion-exchange-induced Bi and K dual-doping of TiOx in molten salts for high-performance electrochemical nitrogen reduction
文献摘要：
Electrocatalytic nitrogen reduction reaction(eNRR)at the ambient conditions is attractive for ammonia(NH3)synthesis due to its energy-efficient and eco-friendly features.However,the extremely strong N≡N triple-bonds in nitrogen molecules and the competitive hydrogen evolution reaction lead to the unsatis-factory NH3 yield and the Faradaic efficiency(FE)of eNRR,making the development of high-performance catalysts with adequate active sites and high selectivity essential for further development of eNRR.Addressing this,we herein report a Bi and K dual-doped titanium oxide(BTO@KTO)material,which is prepared by a cation exchange reaction between K2Ti4O9 and molten BiCl3,for high-performance eNRR catalysts.Benefiting from the controllable molten-salt cation exchange process,a highly active surface containing Bi/K sites and rich oxygen vacancies has been obtained on titanium oxide.Under the synergy of these two merits,an efficient eNRR catalysis,with the NH3 yield rate of 32.02 μg h-1 mgca1t.and the FE of 12.71％,has been achieved,much superior to that of pristine K2Ti4O9.This work thus offers a high-performance electrocatalyst for eNRR,and more importantly,a versatile cation-exchange strategy for effi-ciently manipulating materials'functionalities.
