Defect and interface engineering in metal sulfide catalysts for the electrocatalytic nitrogen reduction reaction: a review

“…To date, numerous electrocatalysts have been explored for the NRR including noble metals, transition metal compounds and metal-free carbonaceous materials. 25–30 Inspired by the structure of natural nitrogenase, which is mainly composed of FeMo and FeV cofactors in the form of metal–S units, metal sulfides have attracted widespread attention since 2018 and great progress has been achieved in this area. 31–34…”

[25][26][27][28][29][30] Inspired by the structure of natural nitrogenase, which is mainly composed of FeMo and FeV cofactors in the form of metal-S units, metal suldes have attracted widespread attention since 2018 and great progress has been achieved in this area. [31][32][33][34] To improve the NRR performance of metal suldes, various material designing strategies such as defect engineering, nanostructure engineering, interface engineering, phase engineering and strain engineering have been developed.…”

Boosting Nitrogen Reduction Reaction via Electronic Coupling of Atomically Dispersed Bismuth with Titanium Nitride Nanorods

“…[ 3 ] Electrocatalytic NRR happening at ambient conditions provides a feasible direction and thus becomes a hot research topic. [ 5 , 6 ] During electrocatalytic NRR, competitive hydrogen evolution reaction (HER) takes place simultaneously, which results in poor NH 3 yield and low Faradaic efficiency (FE), and consequently hinders its large‐scale applications. [ 7 ] Therefore, electrocatalysts with high efficiency and high selectivity are highly demanded for nitrogen neduction reaction (NRR).…”

Ordered Vacancies on the Body-Centered Cubic PdCu Nanocatalysts

“…Ammonia (NH 3 ) has a critical part in farming, industrial, and many chemical products and is known as the next generation of efficient liquid fuel and energy carrier. ,− However, industrial synthesis of NH 3 mainly depends on the Haber-Bosch process, which requires high energy consumption and huge CO 2 emissions under high temperature and pressure conditions. − In recent years, electrochemical nitrogen reduction reaction (NRR) provides a clean, safe, and environmentally friendly way to synthesize NH 3 at room temperature and pressure. ,− Therefore, the high efficiency of NRR requires high conversion, high selectivity, and stable electrocatalysts It is found that among different NRR electrocatalysts, the better nitrogen reduction activity of Pd-based nanomaterials under low overpotential has attracted wide attention. ,− The ordered structure of body-centered cubic (bcc) PdCu can enhance the binding energy of the catalyst with nitrogen and other intermediates, decrease the activation energy of the reaction, and improve the NRR activity to a certain extent . However, the bcc PdCu material has relatively few active sites and cannot greatly improve the NRR activity.…”
