“…It is well known that smaller particle size with higher specific surface area might lead to better electrocatalytic performance. [73,80] So, the catalytic activity of perovskite oxides also depends on its particle size, specific surface area, and porous structure. Thus, to construct perovskite oxides with special nanostructures (such as nanofiber, [81] nanorods, [82] nanowire, [83] nanotube, [84] nanosphere, [85] nanocube, [86] etc.)…”

solve the energy and environmental problems. The hydrogen production reaction from the electrolysis of water is considered to be the reverse reaction of hydrogen combustion, leading to an energy cycle with zero carbon emission. The electro catalytical water splitting is a green, environmentally friendly, and sustainable way to produce hydrogen. [2] The electrolysis of water includes the oxygen evolution reaction (OER) at the anode and the hydrogen evolution reaction at the cathode. OER is a four-electron transfer process, which requires high energy to overcome the reaction energy barrier. [3] Therefore, it is of great significance to prepare high-efficiency catalysts to accelerate the OER process. Among many catalysts, noble metal oxides have been considered as the best catalysts for OER, [4] such as IrO 2 and RuO 2 . However, the high cost and low abundance hinder their practical applications on large scale. [3a] Therefore, searching for noble metal-free catalysts with high cost-to-efficiency is necessary.Non-noble transition metals and their compounds have been reported to be active and stable for water oxidation in alkaline solutions. [4] The research on inexpensive and earth-rich alternative catalysts with high activity and long-term stability has been rapidly increasing, especially for 3d-transition metals (i.e., Fe, Co, Ni, etc.)-based oxides, [5] oxyhydrates, [6] perovskites, [7] phosphides, [8] nitrides, [9] selenide, [10] and sulfides. [11] Among various non-precious transition metal-based catalysts, perovskite oxides have been particularly interesting because of their low cost, high flexibility with abundant elemental compositions, and tunable electronic structures. Some of perovskite catalysts showed comparable or even higher catalytic performance to/than the noble metal oxide catalysts, such as IrO 2 and RuO 2 . They have a general formula ABO 3 , where A is an alkaline earth metal (Ba, Sr, etc.), alkali metal (Li, Na, etc.), or rare earth metal atom (La, Pr, etc.) and B is a transition metal atom (Mn, Co, Fe, Ni, etc.) (Figure 1). In the unit cell, the A-position cation is positively charged with 12-fold oxygen coordination, while the B-position cation is positively charged with sixfold oxygen coordination. The substitution of A and/or B cations can modify the physical (e.g., electronic structure), chemical (e.g., oxidation state), and catalytic properties. In addition, a series of perovskite derivatives with different crystal structures, including double perovskites (A 2 B 2 O 6 ), [12] triple perovskites (A 3 B 3 O 9 ), [13] quadruple perovskites (A 4 B 4 O 12 ), [14] and Ruddlesden-Popper perovskites (A n+1 B n O 3n+1 (n = 1, 2, and 3)), [15] further increase the diversity Perovskite oxides are studied as electrocatalysts for oxygen evolution reactions (OER) because of their low cost, tunable structure, high stability, and good catalytic activity. However, there are two main challenges for most perovskite oxides to be efficient in OER, namely less active sites and low electrical conductivity, ...

“…Nitrogen molecules have moderate bonding strength on metals such as Ru, Au, Fe, Rh, Mo, Sc, Ti, Y, and Zr. [ 153 ] Although the noble metals Pt and Ir have appropriate nitrogen binding energy, their binding strength with hydrogen is higher than that of nitrogen, which will lead to the progress of the HER (competitive reaction). [ 165 ] In addition, metals such as Ti, Y, and Zr have stronger bonding strength with N and can be developed appropriately.…”

High‐entropy alloys (HEAs) have attracted widespread attention in electrocatalysis due to their unique advantages (adjustable composition, complex surface, high tolerance, etc.). They allow for the formation of new and tailorable active sites in multiple elements adjacent to each other, and the interaction can be tailored by rational selection of element configuration and composition. However, it needs to be further explored in catalyst design, the interaction of elements, and the determination of active sites. This review article focuses on the important progress for multi‐sites electrocatalysis in HEAs. The classification is done on the basis of catalytic reaction, including hydrogen evolution reaction, oxygen evolution reaction, oxygen reduction reaction, alcohol oxidation reaction, carbon dioxide reduction reaction, and nitrogen reduction reaction. Based on experiments and theories, a more in‐depth exploration of the high catalytic activity of HEAs will be conducted, including the selection of elements (the special role of each element in catalysis) and the multi‐sites effect. This review can provide the basis for the element selection and design of HEAs in some reactions, to adjust the compositions of HEAs to improve their intrinsic activity. Furthermore, the remaining challenges and future directions for promising research fields are also provided.

Electron transfer plays a major role in chemical reactions and processes, and this is particularly true of catalysis by nanomaterials. The advent of metal nanoparticle (NP) catalysts, recently including atomically precise nanoclusters (NCs) as parts of nanocatalyst devices has brought increased control of the relationship between NP and NC structures and their catalytic functions. Consequently, the molecular definition of these new nanocatalysts has allowed a better understanding and management of various kinds of electron transfer involved in the catalytic processes. This Minireview brings a chemist's view of several major aspects of electron-transfer functions concerning NPs and NCs in catalytic processes. Particular focus concerns the role of NPs and NCs as electron reservoirs and light-induced antenna in catalytic processes from H 2 generation to more complex reactions and sustainable energy production.
