Abstract
The electrochemical nitrogen reduction reaction (eNRR) offers a promising strategy to synthesize ammonia at ambient conditions. However, the selectivity and yield of ammonia are greatly impeded by the slow kinetics of the eNRR and the competing hydrogen evolution reaction (HER). Herein, we find that by growing Ru nanoparticles on rutile TiO, the intimate electronic coupling between Ru nanoparticles and TiO support is able to greatly promote the first protonation of N via an associative mechanism in the eNRR while suppressing the HER, resulting in a greatly improved ammonia Faradaic efficiency of 40.7% and yield of 10.4 μg h cm at −0.15 V versus the reversible hydrogen electrode (RHE) in 0.5 M KSO aqueous solution at room temperature and ambient pressure. Our work provides a general approach to achieve selective electrochemical reaction by controlling the binding strength of reactive intermediates via interface engineering.
