“…Both of the samples consist of elements Fe, V, O, N, and C, while the element P only exists in the sample after phosphating process. The Fe 2p spectrum presented in Figure S9A can be assigned to the Fe 3+ 2p 3/2 (713.3 eV), Fe 2+ 2p 3/2 (710.8 eV), Fe 3+ 2p 1/2 (727.2 eV), Fe 2+ 2p 1/2 (724.2 eV), and their satellite peaks, respectively . The V 2p spectrum is divided into V 4+ 2p 3/2 (516.7 eV), V 4+ 2p 1/2 (523.9 eV), V 3+ 2p 3/2 (515.4 eV), V 3+ 2p 1/2 (522.5 eV), respectively (Figure S9B) .…”

The binary transition metal oxides have attracted great attention because of their considerable energy and power densities. However, they suffer from low reaction kinetics and large volume change, limiting their practical energy applications. The construction of a mesoporous structure with a large surface area, the development of a carbon matrix, as well as heteroatom doping can effectively overcome the above challenges. Herein, the synthesis of phosphorous‐containing Fe2VO4/nitrogen‐doped carbon mesoporous nanowires (P‐Fe2VO4/NCMNWs) is reported. In this unique structure, the atomic‐level P‐doping could increase the conductivity of Fe2VO4 by reducing its band gap, which is confirmed by DFT calculations. Furthermore, the phosphorus can covalently “bridge” the carbon layer and Fe2VO4 through P−C and Fe−O−P bondings. As a result, this anode material exhibits a high capacity (1002 mA h g−1 at 0.5 A g−1 after 250 cycles), excellent rate performance (448 mA h g−1 at 10 A g−1), and prominent long‐term cycling stability (533 mA h g−1 at 5 A g−1 after 500 cycles, 364 mA h g−1 at 10 A g−1 after 1000 cycles). All of these attractive features make the P‐Fe2VO4/NCMNWs a promising electrode material for high‐performance lithium‐ion batteries.

“…According to literatures, Fe 3+ Lewis acid sites (LAS) are active sites for selective conversion of H2S to sulfur [50,51]. In order to understand how acetic acid acts as a regulator to affect desulfurization, the surface acidic properties of MIL-53(Fe)-xH were characterized by DRIFTS technique (Fig.…”

“…To further investigate the selective oxidation of H 2 S to sulfur, the same group prepared a porous MIL−100(Fe) with coordinatively unsaturated (CUS) Fe 2+ /Fe 3+ sites (CUS-MIL−100(Fe)) [69]. It was reported that the functionalized materials exhibited high desulfurization performance and 100% sulfur selectivity at a temperature range of 100-190 • C and space velocity of 6400 h −1 , outperforming both the commercial Fe 2 O 3 and MIL−100(Fe).…”

Hydrogen Sulfide (H2S) Removal via MOFs

The removal of the environmentally toxic and corrosive hydrogen sulfide (H2S) from gas streams with varying overall pressure and H2S concentration is a long-standing challenge faced by the oil and gas industries. The present work focuses on H2S capture using a relatively new type of material, namely metal-organic frameworks (MOFs), in an effort to shed light on their potential as adsorbents in the field of gas storage and separation. MOFs hold great promise as they make possible the design of structures from organic and inorganic units, but also as they have provided an answer to a long-term challenging objective, i.e., how to design extended structures of materials. Moreover, in designing MOFs, one may functionalize the organic units and thus, in essence, create pores with different functionalities, and also to expand the pores in order to increase pore openings. The work presented herein provides a detailed discussion, by thoroughly combining the existing literature on new developments in MOFs for H2S removal, and tries to provide insight into new areas for further research.
