splitting (2H 2 O → 2H 2 + O 2 ), consisting of hydrogen evolution and oxygen evolution reaction (HER/OER), can convert electricity to chemical energy in H 2 and O 2 for further energy applications. The practical application of overall water splitting, however, is still limited due to the lack of effective and stable catalysts to reduce reaction energy barrier and enhance Faraday efficient for both reactions. [6][7][8][9][10] Different materials have been studied for overall water splitting catalysis, like metal chalcogenides, metal carbides, oxides, etc. The transition metal carbides, especially graphene, have a better electroconductivity, ductility, and high surface area which display excellent performance in water splitting. [11][12][13] Oxides as another abundant species on the earth also show better water splitting performance, but their stability in hard media is not very good. [14][15][16] The layered double hydroxides (LDH) with unique structure, abundant interstratified electrons and channels for intermediate adsorption and desorption display wonderful water splitting performance. [17][18][19][20] Additionally, the metalorganic frameworks (MOFs) and their based nanocrystals as newly nanomaterials have got much attention in various fields, but their structure limited the active sites exposure for the complete coordinative metal sites. [21][22][23][24][25] Therefore, it is important to enable the cost-effective, large-scale production of these catalysts, and further improve the performance and efficiency of overall water splitting.Transition metal chalcogenides have many different compositions with various lattice structure, while those materials also have unique electronic structures. [26] Based on those superior properties, the transition metal chalcogenides show promising application in many energy applications, [27] such as electrochemical catalysis, photocatalysis, metal-air batteries, and other energy conversion reactions. Especially for their abundant defects sties, [26][27][28] tunable electronic structure, [29][30][31][32] and various morphology, [33][34][35][36][37] the transition metal chalcogenides exhibit boosting performance for water splitting. However, they still have some disadvantages, such as poor conductivity, activity, and stability, in water splitting limited their large-scale industrial application. [38][39][40][41][42] How to synthesize the active and stable transition metal chalcogenides is still a big challenge for wide application. In this Review, the several promising strategies are designed to prepare the active and stable transition metal chalcogenides (Scheme 1). → 2H 2 + O 2 ) is a very promising avenue to effectively and environmentally friendly produce highly pure hydrogen (H 2 ) and oxygen (O 2 ) at a large scale. Different materials have been developed to enhance the efficiency for water splitting. Among them, chalcogenides with unique atomic arrangement and high electronic transport show interesting catalytic properties in various electrochemical reactions, such as the ...

asymmetrical distribution of lithium resource. [3,4] On the other hand, sodiumion batteries (SIBs) have attracted great attention due to its abundant sodium resource, low cost, and the similar electrochemical reaction to LIBs, which is considered as the promising battery technology for large-scale energy storage applications. [5,6] But the commercial graphite does not work for SIBs as its interlayers are incapable to accommodate the sodium ions with larger ionic size. [7] As a result, one promising step to make the technological advancements is to develop the novel anode materials with both lithium and sodium storage ability.In this regard, transition metal oxides (M a O b , M = Mn, Fe, Co, Ni, Cu, etc.) based on the conversion reaction mechanism have been widely explored as the potential anode materials for LIBs and SIBs. Compared to graphite, transition metal oxides can provide higher theoretical specific capacity and higher safety, because the higher reaction potential can eliminate the lithium/sodium dendrite problem. [8][9][10][11][12][13][14][15] As an important member in the transition metal oxide family, transition metal vanadate has attracted much attention due to the multivalent properties of vanadium, which could deliver considerable capacity based on the multielectron transfer. [16,17] Additionally, the vanadium oxide presents strong VO bond during electrochemical process, suggesting the smaller volume change compared with traditional conversion-type electrodes. [18] For LIBs application, it is reported that the vanadium oxide can store lithium ions on the basis of the intercalation reaction mechanism, and provide the reaction sites for the conversion reaction between transition metal and metal oxide, preventing the aggregation of the obtained highly active metal nanograins, improving the cycling performance of the active material. [19,20] Furthermore, the binary metal oxide could exhibit higher electrochemical activity compared to the single metal oxide electrode. [21] Calcium vanadate nanowires have been synthesized as a novel sodium-ion anode material, which delivered a superior cycling performance (1600 cycles), excellent rate performance (5000 mA g −1 ), and an applicable reversible capacity (>300 mA h g −1 ). [16] Lou's group has developed triple-shelled Preventing the aggregation of nanosized electrode materials is a key point to fully utilize the advantage of the high capacity. In this work, a facile and lowcost surface solvation treatment is developed to synthesize Fe 2 VO 4 hierarchical porous microparticles, which efficiently prevents the aggregation of the Fe 2 VO 4 primary nanoparticles. The reaction between alcohol molecules and surface hydroxy groups is confirmed by density functional theory calculations and Fourier transform infrared spectroscopy. The electrochemical mechanism of Fe 2 VO 4 as lithium-ion battery anode is characterized by in situ X-ray diffraction for the first time. This electrode material is capable of delivering a high reversible discharge capacity of 799 mA h g −1 ...

In the scenario of renewable clean energy gradually replacing fossil energy, grid‐scale energy storage systems are urgently necessary, where Na‐ion batteries (SIBs) could supply crucial support, due to abundant Na raw materials and a similar electrochemical mechanism to Li‐ion batteries. The limited energy density is one of the major challenges hindering the commercialization of SIBs. Alloy‐type anodes with high theoretical capacities provide good opportunities to address this issue. However, these anodes suffer from the large volume expansion and inferior conductivity, which induce rapid capacity fading, poor rate properties, and safety issues. Carbon‐based alloy‐type composites (CAC) have been extensively applied in the effective construction of anodes that improved electrochemical performance, as the carbon component could alleviate the volume change and increase the conductivity. Here, state‐of‐the‐art CAC anode materials applied in SIBs are summarized, including their design principle, characterization, and electrochemical performance. The corresponding alloying mechanism along with its advantages and disadvantages is briefly presented. The crucial roles and working mechanism of the carbon matrix in CAC anodes are discussed in depth. Lastly, the existing challenges and the perspectives are proposed. Such an understanding critically paves the way for tailoring and designing suitable alloy‐type anodes toward practical applications.
