“…Compared with the creation of anion defects in transition metal‐based composites, the higher formation energy makes it more challenging to controllably produce cation vacancies in metal compounds. The methods used to create cation defects in metal complexes include in situ formation, [ 93–96 ] thermal calcination, [ 19,97 ] chemical/electrochemical etching, [ 98–100 ] and plasma treatment. [ 75,101,102 ] In this section, the influence of single type of cation defects such as Co, Fe, and Ni vacancies and multivacancies such as oxygen, Fe, and Co vacancies on the electrochemical reactions will be discussed.…”

“…By embedding MoN nanoparticles (NPs) into N-doped hierarchical porous carbon framework, an excellent Mo vacancy electrocatalyst can be obtained. [47] Compared with the previously reported anion-vacancy catalysts, it has a significant increase in electrical activity (NH 3 yield: 76.9 µg h −1 mg cat.…”

“…In nature, there are three distinguished nitrogenase enzymes with metal‐centered catalytic cofactors of FeMo‐co, FeFe‐co, and VFe‐co, respectively . To mimic the catalytic role of nitrogenase enzymes to achieve the synthesis of NH 3 , a series of potential catalysts containing Fe, Mo, and V elements, including Mo nanofilm, MoS 2 , Mo 2 C, MoO 2 , MoP, MoN, Fe 2 O 3 , FeS x , Fe 3 C, and VN, etc., have been tested for electrochemical NRR under ambient conditions. Recently, both experimental and computational studies showed that a combination of ligand, geometric and synergistic effect of bimetal atoms may facilitate electrochemical NRR .…”
