“…All of the spectra show two main peaks of Cr2p 1/2 (573–580 eV) and Cr2p 3/2 (585–588 eV). The Cr2p1/2 is deconvoluted to three components at 575.6, 576.6 and 578.2 eV, corresponding to Cr 2+ , Cr 3+ and Cr 6+ , respectively . At the same time, the Cr2p3/2 is fitted by three peaks at 585.2, 586.3 and 587.2 eV, corresponding to Cr 2+ , Cr 3+ and Cr 6+ , respectively.…”

BACKGROUND Chemical vapor deposition (CVD) is a promising catalyst preparation method owing to high dispersion and small particles of metallic oxides. Besides, the ZSM‐5 zeolite membrane is used to treat volatile organic compounds (VOCs) due to relatively high contact efficiency, lower bed pressure drop and mass transfer resistance than granular ZSM‐5, giving good stability of the metal catalysts. However, Cr modified ZSM‐5 zeolite membrane prepared by CVD for trichloroethylene (TCE) catalytic oxidation was still not well‐studied. In the present study, a series of Cr(x)/ZSM‐5/PSSF (x = 1, 3, 5 and 7) catalysts with different Cr loadings was prepared by CVD and further characterized by nitrogen gas (N2) adsorption and desorption, X‐ray diffraction (XRD), scanning electron microscopy (SEM), ammonia temperature‐programmed desorption (NH3‐TPD) and X‐ray photoelectron spectroscopy (XPS), as well as catalytic performance for TCE oxidation. RESULTS The results showed that the Cr2O3 species were uniformly dispersed on the surface of ZSM‐5/PSSF, and that the Cr(1)/ZP catalyst exhibited the best catalytic activity for TCE oxidation owing to more Cr6+ species and adsorbed oxygen. It also demonstrated that the Cr(1)/ZP catalyst shows superior catalytic performance for TCE oxidation, giving a T90 that is about 62 °C (c.15%) lower than 1% Cr/ZSM‐5 particle catalyst. Furthermore, it exhibited an excellent stability after online testing at 440 °C for 30 h, and then dropped from 91% to 62% after 95 h, finally remaining at 62% after 120 h. CONCLUSION The study demonstrated that Cr/ZSM‐5 zoelite membrane catalysts prepared by CVD show better catalytic behavior and stability for catalytic oxidation of TCE than Cr/ZSM‐5 zoelite catalysts. © 2019 Society of Chemical Industry

“…The use of MOFs as sacricial templates for the preparation of nanocomposite materials by simple pyrolysis is an increasingly attractive catalyst preparation technique. [29][30][31] Despite this, MOF-derived metal oxides and carbon complex supports have rarely been applied to FA decomposition. [32][33][34] In terms of monometallic Pd catalysts, the size of the Pd NPs especially plays an important role in catalyst activity.…”

“…As a new type of porous crystal material, it is composed of organic ligands and inorganic metal ions. Because of the high specific surface area, high porosity, and adjustable pore size, it widely used in many fields (Yunhong et al, 2017;Chen et al, 2018a;Mínguez Espallargas and Coronado, 2018) including catalysis (Chen et al, 2018c;Zhang et al, 2018c), hydrogen storage (Basdogan and Keskin, 2015;Kim et al, 2015), adsorption (Xue et al, 2013;Oveisi et al, 2018) and energy storage (Nie et al, 2014(Nie et al, , 2015(Nie et al, , 2017bWu and Lou, 2017;Xu et al, 2017;Wang et al, 2018). However, the conductivity of most MOFs is relatively low, and exhibiting low specific capacity as anode materials for lithium ion batteries (Chen et al, 2015).…”

Metal organic frameworks (MOFs) have exhibited promising potential as a new platform for the preparation of porous functional materials for energy storage application. Herein, we report an approach to synthesize ultrathin MoS 2 nanosheets decorated cobalt nanoparticles-containing porous carbon polyhedral with dense nitrogen doped carbon nanotubes (CNTs) backbone, where the ZIF-67 is used as the carbon and nitrogen sources for the growth of CNTs and the self-template for the carbon polyhedron. The composite shows a unique structure in which ultrathin MoS 2 nanosheets are uniformly coated on the ZIF-67 derived carbon polyhedron. Owing to the synergistic effect from composition, morphology, and robust hollow structure composed of interconnected nitrogen doped CNTs networks and cobalt particles, the resulting ZIF-67-C@MoS 2 nanocomposites display high specific capacity of 568.5 mAh g −1 at a current density of 0.2 A g −1 , superior rate capability (291.9 mAh g −1 at 5 A g −1 ), and excellent cycling stability for over 500 cycles as lithium ion batteries anodes. The material also exhibits superior performance as new anodes for potassium ion batteries. The results provide a facile strategy for large-scale synthesis of high performance anode materials through low cost perspective and new insights for designing MOF-derived functional materials with unique structures for energy storage.
