“…† There are two minor peaks at 286.1 eV and 287.5 eV, corresponding to the CN bonds and C-N bonds, respectively, which suggests that N atoms have been doped into the carbon matrix. 4 The N1s spectrum in Fig. S1b † is resolved into four peaks: pyridinic-N (398.4 eV), pyrrolic-N (399.8 eV), graphitic-N (401.1 eV), and pyridinic-N-oxide (403.7 eV), which is consistent with the results of the highresolution C 1s spectra.…”

“…Therefore, it is necessary to use efficient OER catalysts to overcome its slow reaction kinetics. 4 Up to now, a great number of materials have been applied for OER catalysis, 5,6 including various metal alloys, 7 simple oxides such as RuO 2 and IrO 2 , 8 and more complex materials such as combinations of oxides and phosphates. 9,10 Though noble metal-based oxides are considered to be the most excellent OER catalysts with low overpotentials, their high cost and natural scarcity greatly limit their wide application in the field of electrochemical water splitting.…”

“…Margadonna et al reported that PBAs are isotropic materials with nearly zero thermal expansion over a wide temperature range from 4.2 to 300 K. [161] Therefore, the crystal structure could remain stable within the possible temperature range of SIBs, irrespective of the gas releases due to the removal of residual water. [37,162] The most important factor on the materials level for developing PBA-based SIBs for operation under extreme conditions is the robust crystal framework of PBAs. The corresponding crystal structure optimization strategies have been summarized in Section 3.…”

photocopying process took nearly a century from 1843 until the early 1940s, while the detailed crystal structure of PB was first confirmed as cubic by Ludi and co-workers in 1977, which is now widely accepted. [6] Remarkably, the past four decades have witnessed the exploration of PB in more and more new and totally different, but very promising application areas, reaching from rechargeable batteries [7] to catalysis [8] and biosensors, [9] from optically switchable films in electrochromic devices (smart windows) [10] to a helpful nanomaterial for cancer therapy. [11] Due to their excellent redox activity, low cost, and highly reversible phase transitions during the insertion/extraction process of certain cations, PB and PBAs have also been widely investigated as promising active materials for energy storage devices, especially for commercial sodium-ion batteries (SIBs) beyond other batteries system (potassium-ion batteries, [12,13] lithium-ion batteries (LIBs), [14] lithium-sulfur batteries (LI-S), [15] lithium-air batteries, [16] zinc-air batteries, [17] solid-state batteries, [18] etc.) in large-scale stationary energy storage systems in the near future. [19,20] The chemical formulas of PBAs could be represented asHere, A represents a single alkali metal or alkaline earth metal, or a mixture of these metals, while M 1 and M 2 typically are transition metals bonded by CN − bonds to form a 3D open structure with the capability to host element(s) A inside the crystal structure. □ represents the vacancy that is caused by the loss of an M 2 (CN) 6 group and the occupation by coordination water and interstitial water, the species and ionic radii of which are shown in Figure 2a. [21] With the different species and various ratios of A/M 1 /M 2 , the number of family members could reach more than 100, sharing different crystal phases, including monoclinic, [22,23] rhombohedral, [24,25] cubic, [26,27] tetragonal, [28] hexagonal, [29] etc. According to the amount of redox-active sites for battery application, PB and PBAs could be divided into dual-electron transfer type (DE-PBAs: M 1 and M 2 = Mn, Fe, Co) and single-electron transfer type (SE-PBAs: M 1 = Zn, Ni and M 2 = Fe, Co, Mn) with theoretical specific capacity of 170 and 85 mAh g −1 , respectively. [21] Taking the high average voltage and capacity of the DE-PBAs into consideration, they are promising and competitive, even to the level of LiFePO 4 (a well-known cathode material for the LIBs), for high energy density devices (≈450 Wh kg −1 on the material level). On the other hand, the negligible structural distortion and high conductivity of SE-PBAs make them desirable choices for fast-charging and long-life devices. [20,30] Prussian blue analogues (PBAs) have attracted wide attention for their application in the energy storage and conversion field due to their low cost, facile synthesis, and appreciable electrochemical performance. At the present stage, most research on PBAs is focused on their material-level optimization, whereas their properties in practical b...

“…The construction of 2D TMS nanosheets can generate rich electroactive sites due to the large specific surface and abundant active edges. [ 1,23,30 ] Metal–organic frameworks (MOFs), constructed by linking metallic nodes and organic ligand bridges, have attracted considerable attention as templates for synthesizing electrocatalyst materials [ 19,24,31,32 ] due to the characteristics of high surface areas, tunable structure, and highly ordered pores. [ 33 ] Nonetheless, most MOFs possess a blocky morphological structure, which leads to defects such as low metal utilization and accessible surface area and poor intrinsic electrical conductivity.…”

Designing and constructing transition metal sulfides (TMSs) as oxygen evolution reaction (OER) electrocatalysts has been attracting increasing attention. Interface engineering can effectively modify the active sites and promote electron transfer, resulting in improvement of electrocatalytic performance. Here, freestanding heterogeneous CoS2/CoS nanosheets are prepared via a simple one‐step sintering process from a kind of novel hierarchical tremella‐like metal–organic framework (MOF). The formation mechanism of the unique MOF and the heterojunctions between CoS2 and CoS is analyzed. Consequently, the prepared cost‐effective OER electrocatalyst achieves satisfying electrocatalytic efficiencies with a diminutive overpotential of 269 mV at 10 mA cm−2 current density, a small Tafel slope of 52 mV dec−1, and good stability in alkaline solution comparable to RuO2 counterparts. This work opens up a new method for constructing 2D electrocatalysts containing catalytic interfaces with boosted OER performance.
