Abstract:

Owing to their special compositions and structures, ionic liquids (ILs) and deep eutectic solvents (DESs), which are collectively referred to as (quasi) ionic liquids, have unique physical and chemical properties, such as low melting point and vapor pressure. For decades, the use of (quasi) ionic liquids to prepare catalysts with novel structure and excellent performance has attracted wide attention in the field of water electrolysis. Nickel-based electrocatalysts, as a kind of excellent catalysts for water electrolysis, have been extensively studied in (quasi) ionic liquids. In this review, the research progress of nickel-based catalysts in (quasi) ionic liquids is reviewed according to their types. (1) IL or DES-mediated nickel and nickel-based alloy. Due to the good conductivity of (quasi) ionic liquids and the ability to change the order of metal activity, the (quasi) ionic liquids can be used as media to prepare nickel metal catalysts by electrodeposition methods or galvanic replacement reactions. Furthermore, nickel salts can be designed as a component of (quasi) ionic liquids to obtain binary or ternary alloys with other metal salts. (2) IL or DES-mediated nickel (hydro)oxide. The special liquid structures of (quasi) ionic liquids can regulate the growth process of (hydro)oxide, thereby optimizing the structures and properties of catalysts. (3) IL or DES-mediated nickel-based sulfide. (Quasi) ionic liquids can not only be used as media but also be rationally designed as S sources by designing the compositions. (4) IL or DES-mediated nickel-based phosphides. ILs as media and templates can overcome the shortcomings of conventional solvents. Novel structure and pure phase can be obtained. Meanwhile, the anion and cation of ILs can be rationally designed as phosphorus sources to obtain catalyst with excellent catalytic performance. (5) IL or DES-mediated nickel-based nitride. Conventional imidazolium-type IL cations contain nitrogen, while anions can also involve nitrogen. Therefore, the use of ILs to prepare nickel-based nitrides or nitrogen-doped nickel-based catalysts has attracted much attention. In summary, combining with the work of our research group, as described in this review, (quasi) ionic liquids can be used as media, templates, and reactants for preparation of nickel-based catalysts, by which not only excellent performance will be obtained, but also the reaction system is simplified, thus to reduce emissions and realize atomic economy. Finally, the possible future development direction of this field is proposed.
