MoS2 -Based Catalysts for N2 Electroreduction to NH3 - An Overview of MoS2 Optimization Strategies.

The nitrogen reduction reaction (NRR) has become an ideal alternative to the Haber-Bosch process, as NRR possesses, among others, the advantage of operating under ambient conditions and saving energy consumption. The key to efficient NRR is to find a suitable electrocatalyst, which helps to break the strong N≡N bond and improves the reaction selectivity. Molybdenum disulfide (MoS2 ) as an emerging layered two-dimensional material has attracted a mass of attention in various fields. In this minireview, we summarize the optimization strategies of MoS2 -based catalysts which have been developed to improve the weak NRR activity of primitive MoS2 . Some theoretical predictions have also been summarized, which can provide direction for optimizing NRR activity of future MoS2 -based materials. Finally, an outlook about the optimization of MoS2 -based catalysts used in electrochemical N2 fixation are given.
